HD-10~30 digital spring tension testers is a series of instruments specially designed for testing the relations and characteristics between deformation and compressive/tensile loading of a tension spring (stress-strain relationship).
HD series is suitable for both tensile and compression springs.

Features:
- Display with good viewing angle;
- High accuracy and resolution, with minimum reading of 0.001N;
- 3 units available: N, kg, lb;
- Users should set the meter properly using gravitational acceleration to get a more -accurate test result;
- Large memory, save up to 99 sets of data;
- |Peak hold function;
- Peak automatic clearance function;
- Tolerance limit(upper and lower limit);
- USB output; Match synchronous analysis software;
- 1 year warranty and life time maintenance, local service by M&I Instrument;
