• Honeywell's family of ruggedized Q-Flex® accelerometers are designed and built to tolerate demanding measurement-while-drilling (MWD) and wireline environments while providing precision accuracy. Years of downhole experience and an extensive test regime insure that our sensors exhibit superior reliability.

• Two models are available with different temperature ranges, allowing the customer flexibility in selecting the appropriate sensor.
