The COD165 thermoreactor will hold 25 round glass vials with 16 mm

external diameter. It is designed for sample preparation in determining

COD, total phosphorus, total nitrogen, total chromium and other

parameters in water and sludge analysis. The COD165 thermoreactor,

paired with the Thermo Scientific Orion COD reagents and the Thermo

Scientific Orion AQUAfast AQ4000 advanced colorimeter or Thermo

Scientific Orion AQUAfast AQ2040 colorimeter, provide the user with a

complete analytical setup for COD analysis. The Thermo Scientific Orion

AQUAfast AQ3700 colorimeter also performs COD analysis, as well as

nitrogen and phosphate digestion methods.

The COD165 thermoreactor is designed to be highly resistant to chemical

and mechanical corrosion. The heating block that holds the COD vials

allows for very good thermal homogeneity at the selected temperatures. The

temperature of the heating block is microprocessor controlled. The Pt100

temperature probe does not require any calibration, because when the

instrument is turned on, a self test is performed.

The COD165 thermoreactor is equipped with a voltage selector for either

115 V or 230 V. It is accessible on the rear panel of the instrument. Always

check the voltage setting before plugging the instrument into a power

outlet.

The COD165 thermoreactor has five preset work temperatures of

100 °C, 120 °C, 150 °C, 160 °C and 165 °C and four preset run times of

30 minutes, 60 minutes, 120 minutes or continuous time.

The heating block is equipped with over-temperature protection by a

thermostat, which turns off heating when the temperature exceeds 180 °C.

Note: The COD165 thermoreactor is delivered complete with three power

cords; one for 110 to 120 V standard US outlets, one for 220 to 240 V

European outlets and one for 230 V Chinese outlets.

General Information

Thermo Scientiﬁc Orion COD165 Thermoreactor User Guide

The instrument is equipped with a voltage selector, which allows the

connection to either 115 V or 230 V outlets.

After unpacking the unit, position it correctly on the laboratory bench.

Before connecting it to the power supply, check that the power switch is

turned to “0” and check that the data on the unit’s plate corresponds to

that supplied by the electric socket. The unit works at voltages between 90

and 260 V with a frequency of 50 or 60 Hz.

Note: The power switch means that the unit can be completely

disconnected from the power supply when it is not in use, thus reducing

energy consumption.

Use the power switch on the front of the unit to turn the unit on (turned

to “−”). When it is switched on, all the LEDs on the unit blink for few

seconds. When the LEDs are off, the unit is ready to be programmed at

different work temperatures and times.

Control Description

Power Switch The switch lights up when the instrument is turned on.

Start/Temp Key When the Start/Temp key is pressed, the work cycle is started

with the selected temperature and time values, which are

indicated by their corresponding LEDs.

To change the temperature, press the Start/Temp key and

select desired temperature. The temperature setting will scroll

down through the four temperatures and the corresponding

LED will light.

Note: It is possible to select different temperatures if the

programmed temperature has not been reached and the timer

is not started. Once timer has started this key is not operative.

If the selected temperature is lower than the actual

temperature of the heating block when the Start/Temp key is

pressed, the cycle will not start and all the LEDs will turn on

intermittently, indicating an error.

To correct this error, select a higher temperature setting

or allow the block to cool to a temp below the set point

temperature.

Time Key The timer starts when the block reaches the selected

temperature. While the timer is running, the LED will blink and

the Time key is not operative.

Temperature LED When the instrument is turned on the temperature LEDs

are not lit. Once the Start/Temp key is pressed, the selected

temperature LED will light.

All four LEDs will blink if the selected temperature is lower

than the current block temperature.

Time LED When the instrument is turned on the time LEDs are not

lit. Select the desired run time by pressing the Time key. A

blinking time LED indicates that the timer has started.

Start Up

4Thermo Scientiﬁc Orion COD165 Thermoreactor User Guide

When the unit is switched on, press the Start/Temp key to start the work

cycle. The default option is set at 160 °C and 30 minutes, as shown by the

corresponding LED. To select a different temperature, press the Start/Temp

key until the corresponding LED is lit. To select a different time, press the

Time key until the corresponding LED is lit.

Note: It is possible to modify both temperature and time until the

temperature of the heating block reaches the selected temperature and the

run time starts.

When the selected temperature is reached, a beeper will sound

intermittently for 5 seconds. At this time the LED corresponding to the

selected time will start to blink, signalling that the countdown has started.

The end of the countdown will be signaled by a beeper that will sound

continuously for 5 seconds; at the same time the heating element and the

corresponding time and temperature LED will turn off. The instrument is

now ready for a new work cycle.

The instrument will register a black out or a lack of power supply as a

manual stop of the cycle. The work cycle will have to be restarted.

The COD165 thermoreactor will shut down once the timer cycle is

complete. If the power to the instrument is interrupted, the instrument will

automatically end the program that is running and a manual restart

is required.

The COD165 thermoreactor is equipped with an internal thermostat

that will not allow the temperature of the block to exceed 180 °C. If this

temperature is reached the unit will automatically shutdown. The COD165

thermoreactor continuously monitors the block of temperature and if

inconsistent or anomalous readings are observed, the instrument will go

into an alarm mode in which all eight LEDs blink and a beeper sounds.

Chapter 2 Operation

To initiate a cycle on the COD165 thermoreactor, power on the instrument

and press the Start/Temp key.

The default settings are a temperature of 165 °C and a run time of 30

minutes, which will be indicated with the temperature and time LEDs. Use

the Temp or Time key to change the temperature or time setting.

The selected temperature and time settings are shown by the temperature

and time LEDs. It is possible to change both the temperature and time if

the selected temperature has not been reached yet and the timer has not

started. Once the selected temperature has been reached, a beep will sound

intermittently for five seconds. After the beep, the LED corresponding to

the selected time will start to blink, indicating that the timer has started.

The end of the cycle will be indicated when the beeper sounds continuously

for five seconds. At the completion of the cycle, the heater is turned off and

the temperature and time LEDs turn off.

A new cycle can be run if the temperature of the heating block is not

greater than the new selected temperature. If this occurs, the instrument

will enter an alarm mode and all of the temperature LEDs will illuminate.

Running a Cycle

6Thermo Scientiﬁc Orion COD165 Thermoreactor User Guide

All the maintenance operations should be performed only after the

instrument has been disconnected from the power supply.

The COD165 thermoreactor is designed to be maintenance-free and only

occasional cleaning needs to be performed with a damp cloth and non-

flammable, non-abrasive detergent.

The heating block is equipped with two fuses connected to the socket,

located on the rear panel. If a fuse replacement is required, the power

supply should be removed and then the fuse panel can be opened with a

screwdriver. See the Electrical Schematic section for the fuse type.

Disposal of this unit should comply with all local, state, and federal

regulations.

The electronic temperature controls within the COD165 thermoreactor are

designed to provide excellent stability and eliminate temperature overruns

or oscillations. The temperature sensor does not require calibration, as a

self-calibration is performed upon power up of the instrument.

The temperature may be monitored using a standard NIST traceable

thermometer with a range of 0 to 250 °C. Place the thermometer in a hole

within the heating block and monitor the temperature.
