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.

Temperature Range:
OM-HL-SH-T: -20 to 70°C (-22 to 158°F)
OM-HL-SH-TH: -20 to 70°C (-22 to 158°F)
OM-HL-SH-EX: -40 to 85°C (-40 to 185°F)
Temperature Accuracy:
OM-HL-SH-T: ±0.5°C
OM-HL-SH-TH: ±0.5°C
OM-HL-SH-EX: ±0.5°C
Record Volume: 43,000 Temperature Points (OM-HL-SH-T) or 43,000 Temperature & 43,000 Humidity Points (OM-HL-SH-TH & OM-HL-SH-EX)
Humidity Range:
OM-HL-SH-TH: 0-95% RH
OM-HL-SH-EX: 0-100% RH

1. Can it display both Temperature and humidity during recording? 2. Can the data be download thro USB to computer and generate excel file?

Asked by: Eric Chung
Thank you for your question. Yes , the logger can display Temp and Humidity while logging and downloaded data can be imported into Excel. Please note that correct part number for Temperature and Humidity is OM-HL-SH-TH.

1) Does the OM-HL-SH-T model come with the same probe as the other models (even though it is only recording temperature)? 2) Can a delay start (either specific date and time or delay timer) be set for beginning recording?

Is there a way to clear the storage on the data logger without connecting it to a computer? I have a "FUL" message on the screen, and do not have the software on my computer.

Asked by: lallen
Thank you for your question. The logger memory can only be deleted when connected to the PC.

I would like to know if the OM-HL-SH-T data logger could be used in an environment prone to dust particles? Additionally can you only ever record 43,000 data points? I also wish to know if it will be better to use the OM-92.

Asked by: TQI21
Thank you for your question. Any logger that monitors humidity can be affected by dust particles and this could affect the readings and eventually may damage the sensor. The correct model for Temp/Rh is OM-HL-SH-TH and it can record 43,000 points for Temperature and Rh.

Do you have any software validation documentation available?

Asked by: Frank B
Thank you for your question. We do not have a software validation program for the OM-HL series. The OM-CP datalogger has a software validation when it is purchased with the OM-CP-SVP-SYSTEM software with it.

Do you have Solidworks models of this available?

Asked by: D Stimens
Thank you for your question. If you are referring to a CAD dwg than unfortunately no, just the dimensions that are in the manual you can download from our website.
