Handheld Water Quality Meter for Field Readings and Calibration
The ART-HH1 is a portable, battery-powered meter for spot checks, vertical profiles and sensor calibration in the field. It powers the connected sensor or sonde, shows readings on a backlit display and stores them for later review. It works on its own, with no internet or telemetry connection.
Use cases
-
Vertical profiling: lower the sonde to see how conditions change with depth
-
Spot checks: quick readings at any site, no telemetry needed
-
Sensor calibration: calibrate each probe on its own
-
Verification and site surveys: check buoy readings and survey sites before deployment
Two models
Choose the Sentinel when you:
-
Reads one sensor at a time: a single sensor such as the ART-ODO1-B or ART-UV254-HL, or one TrackerSonde probe
-
Used for calibration: each probe is calibrated on its own in a small volume of solution
ART-HH1-SO: Complete sonde
-
Connects to the TrackerSonde and reads all installed probes at once, plus temperature
-
Ideal for vertical profiles and multiparameter spot checks
-
For calibration, use the ART-HH1-SI
Key features
-
Stand-alone: No internet or telemetry is needed, because the meter powers the sensor itself.
-
Backlit display: Readings appear on screen as they are taken, easy to read in the field.
-
Stored readings: The meter saves readings, so you can review them back at the office.
-
Depth readout: With a depth sensor connected, the meter shows depth for vertical profiles.
-
Rechargeable: USB charging, with replaceable 18650 lithium-ion batteries for long field days.
-
Custom cables: Longer cables are available for profiling in deeper water.
