Anritsu BR Series Low Temperature Probe

Anritsu BR Series Low Temperature Probe

The Anritsu BR Series is designed for temperature measurement in low-temperature and controlled environments such as freezers, refrigerators, incubators and drying ovens.

Its long, flexible thermocouple construction allows the sensing point to be positioned inside equipment, containers or enclosed spaces while the connected temperature instrument remains outside.

BR Series probes are configurable by thermocouple length, thermocouple type, tape length, cable length and connector.

Low Temperature Measurement

The BR Series covers temperatures from -100°C to 200°C. It can be used for measuring low-temperature air as well as liquids and semi-solid materials where the probe construction is suitable.

The flexible sensor construction makes it useful where a conventional rigid probe cannot easily reach the required measurement position.

Anritsu's current BR product information specifies -100°C to 200°C, ±3.5°C below -40°C, ±2.5°C from -40°C to 200°C and a 1.5-second response time. :contentReference[oaicite:1]{index=1}

Typical BR Series Probe

The BR probe combines a flexible fluororesin-insulated thermocouple section with an optional thin tape thermocouple section.

The tape section can be routed through narrow gaps such as refrigerator or freezer doors while helping reduce interference with door closing.

Thermocouple Length

The first two digits of the BR model number identify the thermocouple length. Lengths are selected in 100 mm increments.

Thermocouple Type

The BR Series can be supplied with either Type K or Type E thermocouple elements.

The thermocouple type should match the input type of the thermometer or temperature indicator used with the probe.

Tape Length

The digit following the thermocouple type identifies the optional tape section.

Cable and Connector Options

Cable Type

The standard BR Series configuration uses TS thermocouple cable.

BR Series Model Configuration

A typical complete model number is: BR-01K-1-TS1-ANP.

The model number identifies the thermocouple length, thermocouple type, tape length, cable and connector.

Models Available

The following table preserves the full grouped Type K model range currently listed for the BR Series on SL Measurement. Equivalent Type E configurations are also available according to the selected probe specification.

Using the BR Series in Refrigerators and Freezers

The flexible BR construction allows the sensing section to be positioned inside a refrigerator or freezer while the temperature indicator remains outside.

Where the optional thin tape section is used, it can pass through a narrow gap with less interference than a conventional round probe cable.

The measurement position should be selected according to the purpose of the test. Air temperature near a door or cooling outlet may differ from the temperature at the centre of the chamber.

Liquid and Semi-Solid Measurement

The BR Series can also be positioned in suitable liquids or semi-solid materials for temperature measurement.

The sensing section should be immersed sufficiently to represent the target temperature while keeping the connector and other components within their allowable temperature limits.

Typical Applications

• Refrigerators
• Freezers
• Cold storage equipment
• Incubators
• Drying ovens
• Environmental test chambers
• Laboratory temperature monitoring
• Liquid temperature measurement
• Semi-solid material measurement
• Temperature testing inside enclosed equipment
