The MX2306 (470350-966) and MX2307 (470350-970) are low-cost, fully integrated soil moisture loggers with convenient bluetooth wireless data offload.

The HOBO MX2302 features external temperature and relative humidity sensors on a 2 m cable.

This precision, self-contained data logger is ideal for measuring concentrations of oxygen in lakes, streams, rivers, estuaries, and coastal waters.

The HOBO MX2501 pH and Temperature Data Logger is designed for long-term monitoring of pH in estuaries, lakes, streams, rivers, and oceans.

Bluetooth logger with external sensor.

Combining high accuracy water level measurements with out-of-the-box convenience, this money-saving kit includes everything needed to start logging right away. It is ideal for monitoring water levels and temperatures in wells, streams, lakes, freshwater wetlands and tidal areas.

Wireless setup and download via bluetooth technology. Lowers the cost of field data collection by providing wireless access to high-accuracy water level and temperature data.

The Universal Optic USB Base Station and couplers are used to offload data from any HOBO® data logger with an Optic USB interface.

Onset’s HOBO MX1102 CO₂ logger makes it more convenient than ever to measure and record CO₂ in buildings and other non-condensing environments.

The HOBO® waterproof shuttle provides convenient readout and relaunching of underwater and outdoor HOBO data loggers with an Optic USB interface, and is waterproof to 20 m (66'). This shuttle can also be used as a base station.

Records state changes, electronic pulses, and mechanical or electrical contact closures from external sensing devices.

Monitor energy and industrial equipment with this 15 channel data logger to quickly detect and address issues relating to HVAC, machinery and other systems.

The Temperature/Relative Humidity data logger records temperature and relative humidity (within 3.5% accuracy) in indoor environments with its integrated sensors.

Ideal for monitoring water levels and temperatures in wells, streams, lakes and freshwater wetlands, as well as barometric pressure.

A cost-effective data logger for measuring salinity, conductivity and temperature in saltwater environments with relatively small changes in salinity (±5000 μS/cm).

Measures and records conductivity and temperature in streams, lakes and other freshwater sources. Recommended for monitoring aquifers for saltwater intrusion and road and agricultural run-off.
