AVAILABLE OPTIONS

Gel Coat (-F Option)

The MS4525DO is designed for non-ionic and clean dry air applications. Select this option for added protection in

high humidity or slightly corrosive environments with the application of a silicone gel elastomer to sensor and

ASIC. For questions concerning media compatibility, contact the factory.

Low Power (-L Option)

Select this option for battery powered or handheld device applications. In this configuration, the sensor and

calibration microcontroller are powered down, drawing a current of ~ 0.6uA (Vs=5.0 VDC). When the master sends

a Read MR (measurement request) command (I2C or SPI); the sensor

is “awaken” and begins the measurement

cycle; data is then placed onto the output registers. The sensor and calibration microcontroller are powered down

again, awaiting the Read DF (data fetch) command from the master.
