Humidity & Temperature Probe Meter
Instruction Manual
1. INTRODUCTION
The 2 in 1 digital Humidity & Temperature Meter has been designed to combine the functions of humidity meter and
temperature meter.
t is an ideal humidity and temperature meter instrument with scores of practical applications for professional and home use.
The Humidity & Temperature Meter is for use a humidity/semiconductor sensor. This operations manual contains general
information and specification.
2. FEATURES
• Mini size
• Fast response time
• Semiconductor sensor for temperature measurements of -20°C to 60°C and -4°F to 140°F with 0.1°C/°F resolution.
• Humidity measurement from 0%RH to 100%RH with 0.1%RH resolution.
• Data hold function.
• M N and MAX Hold function.

4. PANEL DESCRIPTION
(1) Humidity/Air Temperature Probe (Humidity
Sensor and Semiconductor Sensor inside)
(2) LCD Display: 3½ digits LCD display with units
of °C, °F, %RH and low battery “BAT” M N/MAX
HOLD, DATA HOLD
indication.
(3) MAX/M N Recording/Data Hold Button:
MAX/M N: Press MAX/M N/Hold to enter MAX,
M N Recording mode (manual range only). Select
the proper range before selecting MAX M N to
ensure that the MAX/M N reading will not exceed
the testing range. Press once to select M N. Press
again to select MAX. and press again to release
M N/MAX recording function.
Data Hold: Press and hold the button for over 2
seconds to turn on or off data hold function.
The reading will be held when when Data Hold
button is pressed. f the button is pressed again for
over 2 seconds it will release the hold and allow
further measurement.
MAX Hold/M N Hold: Press and hold the button
for over 2 seconds to turn on or off data hold
function.
(4) %RH, °C, °F select button: Press %RH, °C, °F
select button to enter select %RH, °C, °F
measurement.
(5) Power ON/OFF Button: Turn the meter power
ON/OFF
(6) Backlight Button: Turn the meter backlight
ON/OFF
(7) Battery Compartment
5. HUMIDITY AND AIR TEMPERATURE MEASUREMENTS
1. Hold the probe in the area to be tested and allow adequate time for readings to stabilise.
2. Press %RH, °C, °F Select Button to enter select %RH, °C, °F measurement.
3. Read the Relative Humidity and and Air Temperature.
NOTE: Do not immerse the probe in liquid; it is intended for use in air.
Warning: Don’t expose the humidity sensor to direct sunlight (insolation). Don’t tough or manipulate the humidity sensor.
6. BATTERY REPLACEMENT
f te battery icon appears in the LCD display, it indicates that the battery should be replaced. Open the battery case and
replace the exhausted battery with a new battery. (1x 9V PP3 or equivalent)
