HellermannTyton offers intrinsically safe multimeters

June 2018 IS & Ex

The TBM811XEX and TBM812XEX multimeters with a CATIV 1000 V rating from HellermannTyton are designed for hazardous environments such as mining and petrochemical.

The approved explosive protection rating for both instruments is suitable for use in Zone 1 hazardous area. Group I (coal mines) underground and Group II surface applications.

Both of these meters comply to IEC SANS 60079-0:2000 and IEC SANS 60079-11:1999 and include the following markings on the meter: Ex ib I Mb; Ex ib IIC Gb; SAEx MS/09-200X; and Ex ib – Zone 1 where flammable gas can occur in normal operating conditions.

Robust and splash-proof, the meters can be used to measure various electrical parameters. They have four push button type selector switches and a rotary switch. The rotary switch provides a selection of measurement parameters: AC and DC voltage or current (including mirco and nano), frequency, resistance, continuity (with buzzer), capacitance and diode check.

Four push-on terminals allow the circuits to be measured via two colour-coded leads. A 65x47 mm four-digit LCD provides accurate visual readings of the measured parameters, while two fuses protect the meter against excessive input currents. Additional features include: a dual display; data hold/diode tester; beep-jack input warning and a bar graph.
