RC-4H Temperature and Humidity Data Logger Recording Thermometer Hygrometer Detector

Application:

• This data logger is mainly used for temperature and humidity recording during storage and transportation of foodstuff, medicine,chemicals and other products, expecially widely used in all kinds of warehousing, logistics and cold chain, such as refrigerated containers, refrigerated trucks, refrigerated package, cold storage, laboratory, etc.
• it has internal temperature and humidity sensor, and with external temperature sensor, with internal buzzer alarm. If external temperature sensor is connect, temperature measuring will automatically switch to the external temperature sensor.
• Display temperature and humidity, time, over limit alarm, temperature/humidity upper/lower limit, temperature Max./Min. value in the LCD screen. It has one battery, with the CR2450 battery compartment at the back, ease of battery replacement; Rotate the battery cover clockwise to remove the battery by a coin, and rotate and tighten the battery cover counter clockwise after battery replacement.
• Directly connect with computer for data exchange, easy operation.
• It could also be powered by USB cable when connected with PC, and it could upload data even if the battery is out of use.
• Permanent data storage, data could be read and printed by PC data management software

• Temperature measuring range: -30℃ ~ +60℃; external sensor: -40℃ ~ +85℃;
• temperature unit: ℃ or ℉ optional (set ℃or ℉ through data management software, but LCD display ℃ only )
• Temperature Accuracy: -30℃ ~ +60℃, ±1 ℃; others, ±2 ℃
• Humidity measuring: 0 ~ 99% RH
• Humidity accuracy: ±3% RH (25℃, 20 ~ 90% RH), others, ±5% RH
• Resolution: Temperature 0.1℃; Humidity 0.1% RH
• Record capacity: 16000 points(MAX)
• Record interval: 10s ~ 24 hour adjustable
• Sensor: Internal temperature sensor or external sensor probe
• Communication interface: USB interface
• Power supply: inner CR2450 battery or power supply via USB interface
• Battery life: in normal temperature, if the record interval sets as 15 minutes, it would be used above one year.

• After setting the parameters in data management software, press the button for more than for seconds in the status display interface, the symbol "▶" light, and the data logger starts recording. if the symbol ▶ flashes, indicate the data logger is in the status or start time delay.
• if "permit stopping by pressing button" is set in the software, press the button for more than four seconds, the symbol "■" lights, and the data logger stops recording.

• After finishing parameters setting in the temperature data logger data management software, it will clear up the recorded historical data. Please read and save data before parameter setting.
