Overview

ATEX approved scale for precision weighing in dangerous areas

In industrial scene the accurate weighing operation is often necessary even in explosive atmosphere. GZ series can perform reliable weighing operation in explosive atmosphere zone 1 and zone 2. All models can be supplied as "dry-cell battery operation type" for which no complicated installation works are necessary.

 

GZII Series

Intrinsically safe scale (external weight type)

Covering the wide weighing range from 2kg to 200kg, high speed response and stable indication

 

GZH Series

Intrinsically safe scale with built-in weight

Easy calibration, stable measurement are assured with internal weight

 

 

Intrinsical Safety Ex ia IIB Ta4

 

 INDUSTRIAL SCALE EX-PROOF GZII-GZH SERIES

Selectable From Two Types In Power Supply, Power Supply Box Type Or Dry Cell Battery Type

Power Supply Box Type

No earth connection work is necessary

Dry Cell Battery Type, Very Easy to Install

No wiring work is necessary, 150 hours continuous operation

* The replacement of dry cell battery has to be done in safe area

Power Supply Box Type

* The standard length of power supply cable is 5m. It can be extended as option

 

 

Always Keep The Scale In Good Condition

Semi automatic calibration with built-in weight (available only with GZH    (-B) series). GZII(-B) series can be calibrated with external reference weight

 

 

Easy Comperator Function With Two Limit Values Setting

 

Judge the result by displaying the arrow mark as either HI (excessive), OK (appropriate), or LO(insufficient)

 

 

 

Stainless Steel Housing, Tough Body Ideally Fitted To Industrial Scene

Mirrow finish weighing pan available as standard in GZII-(B)2000(C)Ex, 6000(C)Ex, 12K(C)Ex, all models in GZH9-B) series

 

 

Easy Connection To Outside Devices like PC, Printer

Plentiful options are  selectable output options are available only with power supply box type
