Hanna HI981520-01 Temperature Monitor 115 VAC

Hanna HI981520-01 Temperature and pH Monitor (115 VAC)

The Hanna HI981520-01 Temperature Monitor 115 VAC is a compact and durable pH and temperature monitor, designed for continuous measurement in aquaculture, water treatment, laboratories, and environmental monitoring. Featuring manual or automatic calibration, a high-visibility display, and customizable alarm settings, the device ensures accurate real-time feedback on solution pH and temperature.

Built into an IP65-rated enclosure, this monitor is ideal for wall-mount or panel installations in environments requiring dependable and long-term operation.

Features

• Dual Monitoring of pH and Temperature
  Continuously tracks two critical parameters—ideal for applications requiring consistent water quality control.

• Simple, Accurate Calibration Options

  • pH: Manual or automatic two-point calibration using standard buffers (pH 7.01 and 10.01)

  • Temperature: Automatic calibration across 5 to 50 °C

  • Salinity (ppt): Single-point automatic calibration at 35.00 ppt (if applicable probe is used)

• Clear, User-Friendly Display
  Easy-to-read display shows pH and temperature simultaneously with 0.1 unit resolution.

• Customizable High/Low Alarms
  Set upper and lower thresholds for both pH and temperature with enable/disable alarm function to respond quickly to deviations.

• Rugged IP65 Housing
  Provides reliable operation in humid or wet environments—ideal for greenhouse walls, tank areas, and process facilities.

• Flexible Power Input
  Operates on 115-230 VAC via included 12VDC adapter, making it compatible with standard electrical systems.
