HHT31R-230

HHT31R-230 is a 230 Vac powered stroboscope. This digital stroboscope provides reliable and accurate speed measurements as well as stop-motion diagnostic inspection. A rotary encoder enables quick, precise frequency setting from 30 to 14,000 flashes per minute. The crystal-controlled circuitry] eliminates drift and allows readings accurate to 0.1 rpm. “Divide by 2” and “Multiply by 2” buttons let the user check actual rpm. With “Phase +” and “Phase -” buttons, the user can add or subtract internal phase delays to keep the reference viewing target in eyesight. An “Adder Mode” enables visual inspection for misalignment or bent odd-numbered fan blades, propellers, etc. In the “Tach” mode, the unit uses external sensors to measure up to 200,000rpm directly without flashing the strobe. Up to 6 preset memory values can be recalled from memory and the unit recalls the last value measured.

• Electronic switching provides continuous cool operation
• Easy-to-read backlit digital display
• Latching trigger and 1 ⁄4-20 UNC tripod mount allow hands-free
