Water Quality Sensors

Hydrolab Temperature

The Hydrolab Temperature (Temp) Sensor is a high accuracy, factory integrated sensor designed to deliver reliable temperature measurements across a wide range of water quality monitoring applications. As a core component of the Hydrolab multiparameter platform, the temperature sensor plays a critical role in ensuring accurate compensation and performance of other water quality parameters measured in the field.

Factory installed into the HL4 and HL7 water quality meters, the Hydrolab Temperature Sensor provides stable, fast-response temperature data in rivers, lakes, groundwater, estuaries, and industrial water monitoring environments. Its robust design and proven accuracy make it suitable for long-term deployments as well as short-term field surveys where dependable results are essential.

SENSOR COMPATIBILITY

The Hydrolab Temperature Sensor is factory integrated into the following Hydrolab water quality meters:

• Hydrolab HL4
• Hydrolab HL7

This integration ensures seamless operation, eliminates the need for external probes, and guarantees correct sensor alignment and calibration within the Hydrolab system.

TECHNICAL SPECIFICATIONS

Hydrolab Temperature (Temp) Sensors are engineered to provide precise temperature measurement and automatic compensation for multiple water quality parameters, improving overall system accuracy for the following:

• Electrical Conductivity (EC)
• Dissolved Oxygen (LDO)
• Total Dissolved Gas (TDG)
• pH
• Depth
• Ion-Selective Electrodes (ISEs)

SPECIFICATIONS

• Measurement Range:  –5 °C to +50 °C
• Accuracy:  ±0.10 °C
• Resolution:  0.01 °C
• Operating Temperature:  –5 °C to +50 °C

WHY TEMPERATURE MATTERS

Accurate temperature measurement is fundamental to high quality water data.  Many key water quality parameters,, such as including conductivity, dissolved oxygen, and pH, are temperature dependent.  The Hydrolab Temperature Sensor ensures these parameters are automatically compensated in real time, reducing measurement uncertainty and improving data confidence in both field and long-term monitoring applications.

By integrating temperature measurement directly into the Hydrolab HL series sondes, users benefit from consistent performance, reduced maintenance, and reliable results even in variable environmental conditions.

APPLICATIONS

The Hydrolab Temperature Sensor is suited to a wide range of water monitoring applications, including:

• Surface water monitoring (rivers, lakes, reservoirs)
• Groundwater investigations
• Environmental compliance monitoring
• Research and academic studies
• Industrial and process water monitoring
• Long-term unattended deployments

IMPORTANT

Note:  The Hydrolab Temperature Sensor (Temp) is a HL4 and HL7 accessory and cannot be purchased as a standalone product.
