Spring Tester
NANBEI Is Professional On Providing One-step Solution Of Laboratory Instruments And Equipment
NANBEI NTH -50-500 Digital Spring Tester 
Function:
The NTH spring pull pressure test stand is specially design for measuring the stretches and
compression distortion value of spring, and the load relations characteristic.
It is applied in measuring the working load of spring when it on the certain length stretched and compressed.
Parameter:
1:Test spring max unsupported length: 10N~30N is 100mm, 50N~500N is 150mm, 1000N~5000N is 200mm
2:Max distortion value stroke: 10N~30N is 70mm, 50N~500N is 90mm, 1000N~5000N is 150mm
3:Distortion value resolution eH: 0.01mm
4:Distortion value display interface: Five figures and “-” position liquid crystal display;
5:Max working load: According to measuring range;
6:Load resolution eP: 0.02N
7:Platen diameter: 49mm
8:Shows value error: ±1%
9:Power source: Exchanges 220V-50Hz
10:Power: 13W
11:Operating temperature: 20±10℃
12: Storage and transport temperature: -27℃~+70℃
13:Relative humidity: 15%~80%RH.
