Infrared Belt Tension Gauge 10Hz-500Hz | Non-Contact Vibration Frequency Meter | Digital LCD for HVAC, Machinery & Engine Drive Belt Maintenance‌

Measuring Principle: This tensiometer can measure the natural vibration frequency of the belt through the emission and reception of the laser, and then calculate the tension value of the belt by combining the input belt mass and the free belt length. Specifications: Measurement Range : 10Hz~500Hz Input Range: Free Belt Length Max 99.99m; Belt Mass Max 9.999kg/m Digital Sampling Error: <1% Display Error: ±1Hz Total Error: <5% Operating Temperature Range: +10°C~50°C Transportation Temperature Range: -5°C~50°C Unit of Measurement: Metric: m, kg/m, N; Imperial: Inch, lbs/foot, lbf Optical Path Measurement Distance: 3mm~20mm Depth of Split Sensor: About 66mm Power Supply: 4x1.5V AAA (UM-4) Battery Size: Main Unit: 178mmx72mmx34mm Sensor: 124mmx21mmx12mm Weight: 180g (Not Including Battery) Standard Accessories: 1 × Main Unit 1 × Split Sensor 1 × Carrying Case (B04) 1 × Operation Manual

• Using laser sensor, direct measurement, more convenient than mechanical sensor.
• The size of the split sensor is small, which is suitable for measuring in a narrow space.
• Two kinds of sensors selectable, the integrated sensor and the split sensor.
• Metric or imperial units can be used to display readings.
• With automatic power off function.
