The Norbar TruCheck 2 is a cost-effective torque wrench checker that allows torque wrench performance to be monitored and tools to be kept in peak condition. Having limited settable options makes it ideal for non-expert users with click-type torque wrenches. An inbuilt micro USB 2.0 port enables power from any USB power source. Software can be updated remotely, without the need to return the product to Norbar. Supplied with traceable calibration certificate in clockwise direction. A counter-clockwise calibration is available at an additional cost. If you order a UKAS accredited calibration certificate (available at extra cost) this certificate will be provided in place of the traceable calibration certificate.Specification: Adaptors: 1/4in male hex and 1/4in female square driveRange: 0.5-10NmAccuracy: 1% torque reading accuracy (2% when below 10% of range for the 1,100Nm TruCheck 2 model)Display: LCD DisplayTemperature Range: Operating: 0C to +50C, Storage: 20C to +70CAuto Reset Hold Time: 1, 2 or 3 secondsPower Consumption: 0.5WEnvironment: IP 40Weight: 1.4kg Requires 2 x Hexagon Socket Head Cap Screws ISO 4762 - M10 - 12.9 to fix in position (not supplied).
