Digital Thermo Hygrometer - DTM-303A

TECPEL Digital Temperature humidity meter - DTM-303A

Dual row display, with 3 meters extension wire with sensor, Accurate and Reliable

A thermometer measures the temperature of the environment or material that we are operating on. A Hygro thermometer is a device that measures both temperature and relative humidity. Two means help the thermometer to display the signal. First, the digital sensor in infrared models, and secondly the converter that shows the numbers.

DTM-303A Hygro-Thermometer is a multi-functional hygrometer with the features of measuring indoor humidity, indoor/outdoor temperature (℃,℉), max/min temperature and humidity recalling (℃,℉), comfortable and uncomfortable index, and alarm clock function with snooze.

This Hygro thermometer provides:

• Easy to read jumbo display

• Comfortable and uncomfortable index (comfort/warm/cool)

• Temperature unit °F/°C selectable

• Maximum and minimum (°F/°C) temperature and humidity Memory recalling

• Alarm/snooze set

• Dual row display

• 3 meters’ extension wire with sensor

• 2 x 1.5 volt ""AAA"" sized or equivalent batteries

Measurement range:

The DTM-303A measures temperature at -50...+70°C or -58...+158°F , it also could measure relative humidity in 20%...100%RH range.

Accuracy:

This hygro thermometer features temperature accuracy of 1°C or 1.8°F in the temperature range of -20...+70°C or -4...+158°F, but the accuracy outside of this range would be more than 1°C or 1.8°F. Humidity accuracy of the DTM-303A is 3% RH in the range of 30...70%RH and outside of this range the accuracy is 5% RH.

Resolution:

Resolution of a sensor is the smallest difference that it could measure. For this thermometer, resolution is 0.1° for whole temperature range, and 0.1%RH for whole Humidity range.

Operations:

Here is important points you need to know about the DTM-303A operating bottoms, and indictors:

• On/Off: Press once to switch on thermometer and press again to switch off. "Warm", “comfort" or "cool" sign appears at appropriate temperature and humidity.

• °F/°C: Press °F/°C to select desirable temperature unit.

• Max/min: Press once to recall maximum temperature and humidity tested. Max sign shows on the display. Press again to recall minimum temperature and humidity tested. Min sign shows on the display. Unit restores to real time mode automatically after 5 seconds.

• In/Out: Press once to display outdoor measurement. "Out" sign shows on the display. Press again to display indoor measurement. "In" sign shows on the display.

• Low battery indicator: Replace new battery when the low battery indicator appears on the screen.
