KISTERS multi-parameter water quality probes HyQual 200, HyQual 300 and HyQual 300T are your individual complete solutions in water quality analysis. Depending on the chosen model and optional extensions, the sensors can determine a subset or all of the following parameters:

  • Temperature
  • Optical dissolved oxygen
  • Specific conductivity
  • pH
  • ORP
  • Turbidity
  • Total dissolved solids (calculated)
  • Salinity (calculated)
  • Depth (level) up to 50 m
  • Barometric pressure

HyQual stands out for its rugged and compact design and is made from durable materials such as 303 and 316 stainless steel, polyacetal (delrin), PVC, teflon, ABS, titanium, viton, neoprene, silicone, and glass, for deployment even in harsh environments as waste water or industrial water. The probes are simple to calibrate, implement, and use. They provide reliable, stable, and repeatable results.

HyQual probes are known for their exceptional quality. This is why they come with a free extended warranty of 3 years world-wide.

Easy connectivity and deployment

  • For spot measurements, HyQual can be connected to almost any smartphone, tablet or other display device (Android™) via a Bluetooth® wireless technology transceiver. The probe communicates and is powered via its underwater cable connected to the rechargeable transceiver housed in a waterproof (IP67) case.
  • For continuous logging, HyQual probes can be connected via an underwater cable RS-232 /SDI-12 to an external data logger/power supply.
  • For both continuous logging or spot measurement, HyQual has an optional rechargeable external battery pack for a self-contained data logger.

All HyQual versions are enclosed in a waterproof (IP67) case and can be optionally equipped with an SDI-12 or MODBUS interface.

HyQual probes come with an easy-to-use app for accessing functions and data. It offers the usual functions (such as calibrations, parameter selection, snapshot data capture, etc.) plus geofencing, automatic logging, and emailing of data.

  • Rugged and compact design
  • Low maintenance
  • Easy to install and use
  • Several output options like RS-232 (standard) or Bluetooth® wireless technology, SDI-12 and MODBUS (optional)
  • CE-certified
  • Compatible with KISTERS range of data loggers

HyQual is suitable for manual spot checking as well as unattended logging in  

  • Wastewater, groundwater, industrial water, brackish water, seawater
  • Lakes, rivers, estuaries
  • Boreholes
  • Education, research and laboratories
  • Aquaculture
