Hobo Data loggers

HOBO Data Logger products are now used by more than 1,000,000 customers worldwide.

Small, low cost, HOBO U Series Data Loggers record temperature, relative humidity, events, state, light/motor on/off, AC current/voltage, 4-20mA, 0-2.5 VDC, carbon dioxide, gauge/differential pressure, water flow, and air flow/velocity via internal or external inputs. Waterproof Pendant Data Loggers offer low cost data logging of temperature, light intensity, acceleration, and tilt/motion housed in a small waterproof enclosure.

Wireless HOBO ZW Series Data Loggers record temperature, RH, kW, kWh AC current/voltage, 4-20mA, 0-2.5 VDC, carbon dioxide, gauge/differential pressure, water flow, and air flow/velocity via internal or external inputs.
