Product Details

The HT-HR is a small Dual Channel High Resolution (16 bit) Humidity and Temperature data logger housed in a rugged 304 stainless steel case. The humidity and temperature sensors are housed in a 60 micron Stainless Steel filter at the top of the logger. The HT-HR mark 4 uses a Sensirion SHT15 humidity sensor giving ±2.0%RH accuracy from 10%RH to 90%RH.

The logger contains an integral internal temperature sensor which is logged separately to humidity.

Logging can be configured to: start on time, immediate start, start on condition, stop when full, loop around (overwrite oldest data).

 Features

  • Temperature & Humidity can be set to any combination of Point, Average, Maximum & Minimum readings.
  • The data from any logger that records Temperature and Relative Humidity can be processed, by the Omni7 software, to add Absolute Humidity and/or Dew Point readings to the data.
  • The logger can be set to log Humidity only, Temperature only or both Humidity and Temperature.
  • The battery voltage of the logger can be logged if required.
  • The logger can be run in either “Stop when memory is Full”, “Loop Around” mode or set to stop at a future time.
  • The logger can be started “Now” or started at a given time in the future.
  • The data from any logger that records Temperature can be processed, by the Omni7 software, to give daily, weekly and monthly accumulated Grow Degree Day reports for a wide range of horticultural crops.

A DLC3USB [USB] download cable (2m) is required to connect the HT-HR to a computer.

AlarmsTwo independent Alarms
Triggered on any combination of six user configurable Alarm Conditions
Both alarms can be configured to send SMS messages
Alarms can be visually checked using the Omni7 software
Start modesStart immediately
Start on date/time
Start on condition (eg Humidity < 30%RH)
Stop modesStop when memory is full
Stop on date/time
Loop around (continues logging)
Logging modesEach channel can be set to log any combination of:
- Point readings          - Average reading
-Maximum reading     - Minimum reading
Warning: When using the Average, Maximum or Minimum reading(s), the logger reads the attached sensor(s) every second. This will reduce battery life.
BatteryOne to Five year life depending on usage as above
Using the logger in temperatures below -5°C (23°F) will reduce battery life
