Altek 942 Frequency Calibrator

Altek 942 is a laboratory-accurate frequency calibrator offering CPH, CPM, Hz, and kHz ranges with ±0.001% accuracy. It calibrates totalizers, flowmeters, frequency transmitters, and integrators, provides selectable sine/square outputs with adjustable amplitude, recalls min/max frequency, includes Quik-Chek presets, and runs long on AA batteries.

Product Overview

• Laboratory accurate ±0.001% (10 PPM); six ranges: CPH, CPM, Hz, kHz.
• Calibrates flowmeters, totalizers, frequency transmitters, and integrators; outputs sine, zero crossing, or zero-based square waves.
• Adjustable amplitude 50 mV to 12 V p-p; built-in totalizer; min/max frequency recall; Quik-Chek.

Altek 942 delivers ±0.001% accuracy across CPH, CPM, Hz, and kHz ranges. Calibrate flowmeters, totalizers, frequency transmitters, and integrators with selectable sine or square outputs, adjustable 50 mV to 12 V amplitude, min/max frequency recall, Quik-Chek presets, built-in totalizer, and long battery life. Reads all waveforms, 40 mV–240 V peak.

Target Market

Ideal for instrumentation technicians, calibration labs, and process engineers in water/wastewater, oil and gas, chemical, power generation, and manufacturing. Used during commissioning, routine calibration, and troubleshooting of flowmeters, totalizers, frequency transmitters, and integrators where precise pulse and frequency control is required.
