Description

The reliable and accurate RH32 Series Temperature/Relative Humidity Meters measure and display both temperature from -10 to 50°C (14 to 122°F) and humidity from 0-100% RH. It has the datalogging capability to store up to 8000 readings of both temperature and humidity into memory. The data can be stored either manually or automatically from once a minute to once an hour over a specified time period entered in calendar time (month/day/hours/mins).

Three types of sensors are available. A built-in sensor, a small separate sensor and a probe type sensors. The model comes with one type of sensor when purchased, but all sensors can plug into the units and are easily interchangeable without special calibration.

RS232C communication interface is available along with optional software for analysis of measured data. The software allows for easy transfer of data to a computer either in real time or of data stored in memory. A trend graph can be displayed on the computer screen. The data can also be exported to a spreadsheet.

The RS485 communication allows up to 30 units to be connected to a computer for real time temperature/humidity measurement applications.

Relative humidity or dew-point temperature reading (°C or °F)
Rated 5 out of 5 by from Omega Handheld Humidity Meter. This is the 3rd Omega Humidity meter we have purchased and have found them very reliable, durable and accurate. The small form factor makes them easy to use in our lab and in the field. Only issue is they tend to eat batteries, so I suggest getting the DC power supply that goes with this unit.

Hi How can I connect to it via serial interface is there a programming / commands reference or manual?

Asked by: Mina
There is Software and a Communication cable available in the accessories to use with the RH32. Call in to the temperature department for any other questions.
