Surface Resistance Meter: SRM330 

 
The SRM330 is a digital surface resistance test kit designed to test all 
conductive, anti-static and static dissipative surfaces for electrical re-
sistivity/resistance according to EOS/ESD, CECC, ANSI, ASTM test 
procedures. It accurately and quickly measures resistance between 
two points (RTT) and surface to ground resistance (RTG). Equipped 
with built-in parallel electrodes for quick surface measurements and 
two banana jacks for connection for two external probes.  Included in 

the kit are two “Press & Test” travel probes that similar the 5lbs of pres-

sure necessary for some measurements.  Suitable for factory audits 
and test lab evaluations. 

 
Features include:  

 

10v and 100v range voltage selection

 

 

Two “Press & Test” lightweight travel probes 

 

 

Built in resistivity probes 

 

Carrying case 

The

 

SRM330meets periodic test requirements per Compliance Verifi-

cation ESD TR53 and conforms to ANSI/EOS/ESD (S4.1, S7.1, S12.1, 
S2.1).
