Operation

1. To ensure WICK (A) is saturated with water and covers spirit reservoir on WET BULB

THERMOMETER (D), remove END CAP (B) and immerse PSYCHROMETER BODY (C) up

to the thermometer reservoirs until WICK is thoroughly wetted.

2. Fill END CAP with water and replace; tighten just enough to prevent leakage. Be sure

reservoir on other THERMOMETER (F) is dry.

3. Pull TUBE (E) clear of BODY so BODY can swivel.

4. Holding TUBE, whirl body two to three revolutions per second (120 to 180 RPM).

5. Continue whirling until temperatures stabilize (1-½ minutes is usually ample).

6. Immediately read WET BULB THERMOMETER (D) and then DRY BULB THERMOMETER

(F). (See application instructions.)

7. Set wet and dry bulb temperatures opposite each other on side rule type calculator

scales, sliding BODY into TUBE as required.

8. Read % R.H. (percent relative humidity) indicated by arrowhead on lower scale.

Application

Wet-bulb temperatures should be read first and as quickly as possible for highest

accuracy. Delay in reading may cause error. In addition, the wick must be kept clean,

saturated with water, and whirled long enough to stabilize temperatures.

The range of the psychrometer is from 10% to 100% R.H., for dry-bulb temperatures of

30° to 100°F (–5° to 50°C).

In addition to the above instructions, barometric pressure and other factors will influence

exact relative humidity determinations to a very minor degree. For precise work, use a

psychrometric chart or set of tables such as W.B. No. 235 “Psychrometric Tables for

Obtaining the Vapor Pressure, Relative Humidity, and Temperature of Dew Point,” which

can be purchased from the Superintendent of Documents, United States Government

Printing Office, Washington, D.C. The accuracy of the Psychrometer, however, is

satisfactory for all except the most exacting work.

Maintenance

WICK (A) should be kept clean. When dirty, cut off WICK below WET BULB THERMOMETER

(D) and pull clean section out of END CAP (B) and slide over bulb on WET BULB

THERMOMETER.

A WICK REPLACEMENT KIT may be purchased separately (refer to parts list). One or two

extra WICKS may be kept in END CAP and will help retain moisture longer. Pack WICKS

loosely to allow thorough water saturation and ample water supply to the WET BULB

THERMOMETER.

THERMOMETERS (D) and (F) are replaceable by backing off SCREWS (G) and loosening

THERMOMETER CLIPS (H). To separate BODY (C) and TUBE (E), drive ROLL PIN (I) out of

eye in PLUG AND SWIVEL ASSEMBLY, which then may be slid out back end of TUBE.
