Environmental Measuring Systems (EMS) products

Small watertight datalogger designed for three sensors with voltage output signal, suitable for harsh environment (typically soil moisture sensors). The connectors are approved for immersion in water. Infrared data access.

One channel datalogger designed for the independent measurement of voltage signals. Watertight, infrared data access. Suitable for the registration of radiation sensors, temperature difference with thermocouples and of any externally powered sensors with voltage output.

Small watertight datalogger intended for the measurement with position sensors with potentiometers. Most often used for registering dendrometers.

Event recorder – this datalogger registers the exact time of pulse occurrence. It suits mainly to tipping bucket or tipping spoon rain gauges. It gives excellent high time (1 second) resolution data for analyze of precipitation dynamics. Battery duration for more than ten years, memory capacity ca six years.

Datalogger EdgeBox V12 is battery operated equipment for automatic data recording in both field and laboratory applications. The logger is made for easy installation in any enclosure with DIN-rail holders. It is powered by two alkaline AA 1.5 V batteries although an external power supply can be used, too.

Minikins are small dataloggers with built-in sensors for the measurement of environmental variables. They are intended for long-term monitoring. The measuring accuracy, memory size and the overall design overruns most of the similar products. The datalogger case is watertight, made from stainless steel and high-density polyethylene. The humidity sensor has sintered stainless steel filter to protect it against splashing. The non-volatile data memory can store typically 60,000 measured values what is enough for more than two years of storing of three measured variables in hourly intervals. According to measuring mode, the oldest data in the memory can be overwritten with the newest ones or the measurement stops when the memory is full.
