RMS digital multimeter with high transient protection

“KUSAM-MECO”, one of the pioneers of digital multimeters and clampmeters in India have introduced a new intrinsically safe True RMS Digital Multimeter with PC interface model KM 822sEX. It has high transient protection of 12 KV (1.2/50mS) lightning surge. It has a 4 digit 10,000 counts large easy to read, backlight dual display. EX marking on meter i.e. Ex ib I Mb, Ex ib IIC Gb, SAEx MS/09-291X, Ex ib falls under Zone 1 which is an area where flammable gas can occur in normal operating conditions.

The measuring functions include:

• DC/AC Voltage: 60mV ~ 1000V
• DC/AC Current : 600micro A ~ 10A
• Resistance : 0.1Ohm ~ 60MOhms
• Frequency : 5Hz ~ 1MHz
• Capacitance : 60nF ~ 20mF
• Diode, continuity, duty cycle function

In addition, it features splash/drop proof, intrinsically safe, beep-jack audible & visible input warning, relative zero mode, data hold, ex-rating, Ex ib I/IIC T6. It has (optional) PC interface for downloading the data in computer via USB cable & Software.

These meters comply with IEC SANS 600790:2000 & IEC SANS 60079-11:1999, which is for electrical apparatus for explosive gas atmospheres. Part 0 (general requirements) and part 1 (intrinsic). The approved explosive protection rating of this equipment is suitable for use in Zone1 hazardous area. Group I (coal mines) underground & Group II (surface).
