Telemetry and Data Recorders

Data Loggers are stand-alone systems utilized for continuous monitoring and data managing. The on-board memory makes it possible for many data loggers to store data for days, weeks, months and even years. The data sampling rate is programmable to adequately meet the demand at each site. Data stored in the memory can be retrieved on-site via a laptop or handheld device depending on your data logger's capabilities, additionally data can be transmitted wireless to a server via cellular or satellite, data transmitted wireless is normally available for viewing online and can be accessed from any device connected to the internet. 

The DT82E is your ideal solution for applications where monitoring between one and 6 sensors is required.The DT82E comes with a rugged design, perfect for environmental applications. Connect up to (6) 4-20 mA sensors. The built-in 16 character LCD displays a variety of function including data for each active channel. Historical data can be saved to a removable memory stick so carrying a computer to the job-site is not necessary.

The PT2X-BV is a special version of the PT2X designed to measure barometric and vacuum pressure in reference to absolute pressure, along with temperature and time. Barometric pressure is measured in the range of 600 to 1100 millibars.

The PT2X-BV is available in two enclosures – either an ABS weather-proof box or a stainless steel tube, the tube version is available with either a solid end cone or an NPT end cone for connecting to piping.
