Overview: As a special-purpose instrument, this testing machine is used to test amount of deformation and characteristic of load relation of extension and compression springs. It can be applied to the testing of working load of extension and compression springs under certain working length. Advanced and highly integrated chip microprocessor is adopted by this machine, which also has liquid crystal display (English) and metal enclosure. Technical Specifications * Maximum testing load: 10N/ 1Kg/ 2.2Lb * Minimum resolution:0.001N/0.0001Kg/0.0001Lb * Diameter of the platen:34mm * Maximum free length of measurable spring: 80mm * Length of travel of the displacement scale: 60mm * Division value of the displacement scale: 0.01mm * Indication error: ±1% * Power Supply: AC 110-220V, 50HZ-60HZ * Working temperature: 20±10℃; Relative temperature: 15%～80%RH * Temperature of storage and transportation: -27℃～+70℃ * Size:490x280x300mm Functional Features: * Liquid crystal display (English); better Human Machine Interface (HMI) * Three kinds of measurement units can be selected(N, Lb and Kg); inter-conversion is available * The user can independently set up acceleration of gravity of the place of usage. In this way, the testing and unit conversion would be more accurate * The user can freely shift among the following three patterns: Real-time and peak-value patterns and the pattern of automatic peak value * It has the function of client setup and free setup of upper and lower limits (corresponding to audible and visual alarms), storage value, holding value, automatic storage time of peak value, automatic shutdown time (non-operation), etc Spring Extension and Compression Tester 10N Spring Extension and Compression Tester 20N Spring Extension and Compression Tester 30N Spring Extension and Compression Tester 50N Spring Extension and Compression Tester 100N Spring Extension and Compression Tester 150N Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Price $1,520.00$1,520.00 $1,520.00$1,520.00 $1,520.00$1,520.00 $1,700.00$1,700.00 $1,700.00$1,700.00 $1,700.00$1,700.00 Maximum testing load 10N/ 1Kg/ 2.2Lb 20N/ 2Kg/ 4.5Lb 30N/ 3Kg/ 6.5Lb 50N/ 5Kg/ 11Lb 100N/ 10Kg/ 22Lb 150N/ 15Kg/ 33Lb Minimum resolution 0.001N/0.0001Kg/0.0001Lb 0.001N/0.0001Kg/0.0001Lb 0.001N/0.0001Kg/0.0001Lb 0.001N/0.0001Kg/0.0001Lb 0.01N/0.001Kg/0.001Lb 0.01N/0.001Kg/0.001Lb Diameter of the platen 34mm 34mm 34mm 48mm 48mm 48mm Maximum free length of measurable spring 80mm 80mm 80mm 150mm 150mm 150mm Length of travel of the displacement scale 60mm 60mm 60mm 90mm 90mm 90mm Division value of the displacement scale 0.01mm 0.01mm 0.01mm 0.01mm 0.01mm 0.01mm
