1. resistance test. 2. Three ways to simultaneously display the resistance or material properties. 3. Environment temperature measurement. 4. Temperature unit switch. 5. Data holding. LCD backlight. Automatic shutdown. Portable Resistance Meter WT311 Handheld LED Display Resistance Test High Accuracy Backlight Resistance Measuring Tools: The resistance can be measured by attaching two parallel electrodes of the instrument to the of the measured object. Thus you can determine whether the measured object is a conductor, anti-static material, or an insulator. The instrument is particularly suitable for a variety of anti-static areas. Specifications: Resistance measurement range: 0.1x10 - 1.5x10 Resistance measurement accuracy: 10% Resistance measurement response time: 1s Temperature Measurement Range: 0 -50 / 32-122 Temperature measurement accuracy: 2/3.6 Dimension: 63.6x31x125.8cm Weight:122g Scope Of Application: This product is a resistance tester which is an instrument for testing the resistance of objects. It is widely used in microelectronics, medicine, aerospace, precision machinery and other fields. Power Supply:1 x 9V 6F22 battery (Not included batteries) Color:Black & Red Material:plastic Package Contents: 1set * WT311 resistance tester Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
