OM-HL-SH Operation Instruction
The OM-HL-SH Series of portable temperature and temperature/humidity data loggers are easy-to use, versatile and price competitive devices which can be used for a wide range of logging applications including coolers, freezers, greenhouses, museums, laboratories, shipping containers, warehouses, environmental monitoring and food storage.

With 100~200ms sensor response time, these data loggers are capable of sampling as fast as 1 second and logging between once every 2 seconds to 24 hours. Both Models OM-HL-SH-T and OM-HL-SH-TH can store a total of 43,000 temperature only or 43,000 temperature & 43,000 humidity measurements in memory. Excellent user experience and cost effective makes this OM-HL-SH series one of the best temperature/humidity logging solutions in the market.

NIST Traceable calibration model OM-HL-SH-TH-CAL is available to order as well as the external probe model OM-HL-SH-EX coming with standard 3 meter long IP65 temperature and humidity probe. See the following picture of EX model.

Is there a way to increase the speed of data download? When the device is full, it takes around 15 minutes to get all the data to my PC. The OM-62 did the same in a few seconds.

Asked by: Temp_logger
Hello Regarding your question, the download speed cannot be modified as it is dependent on the USB port capability

How often these data loggers should be calibrated? do you offer initial three point calibration service?

Asked by: Rickhenry
Thank you for your question. It is more economical to purchase new calibrated logger every year because recalibration would be more expensive and also not available. Unfortunately, 3 point custom calibration is not available.
