The GP-HR is a small High Resolution (12 bit) multi purpose data logger housed in a rugged 19.05mm 304 stainless steel case, that can be configured to accept input from a wide variety of sources including:
- Voltage (DC)
- Current (DC) including 4~20mA
- Pressure Probes
- Flow Sensors
- Frequency
- Tipping Bucket Rain Gauges
- Solar Radiation Sensors
- Light Sensor
- Leaf Wetness Sensor
- Soil Water Tension Probes
- Wind Speed Probes
- Wind Direction Sensors
The GP-HR also has an internal temperature sensor for convenient logging of ambient temperature if desired. Logging can be configured to: start on time, immediate start, stop when full, loop around (overwrite oldest data).
The GP-HR (mark 4) features a storage capacity of over 1,000,000 8bit samples; or over 500,000 12bit samples, as well as a user replaceable battery!

* Logging Thermocouple inputs with the GP-HR:
A lot of people say thermocouple to mean temperature probes, where as if the temperature range they are measuring is between -50°C and +200°C, then RTD Pt1000 is more accurate and cheaper to implement than thermocouple. Thermocouples are ideal for high temperature ranges. The Pt3-PSprobe set has three RTD Pt1000 temperature probes, ranged at -50~130°C for use with the GP-HR.
The only way that the GP-HR can accept a thermocouple signal is via an intermediary transmitter like the XU Series with an output signal of 4~20mA. An mA#-PS adaptor cable for each input from the XU Series transmitter(s) to the GP-HR is also required (with the correct number of inputs [1~3]).
The Tc-HR or Tc-LCD data loggers are available for logging 1x Thermocouple input.
A DLC3USB [USB] download cable (2m) is required to connect the GP-HR to a computer.
This unit can be added to one of our Small and Medium Weather Systems
