LUDLUM 193 MicroR Survey Meter (0 ~ 5 µR/hr - 0 ~ 5000 µR/hr)

Application: Low-level (microR) gamma survey

Compatible Detectors: Scintillation

Linearity: Reading within 10% of true value

Meter Scale: 0 to 5 µR/hr provides an overall range of 0 to 5000 µR/hr (other meter scales available)

Meter: 1 mA, 6.4 cm (2.5 in.) scale, pivot-and-jewel suspension

Alarm: The alarm is adjustable from 10% of full meter scale to greater than full meter scale. An alarm is manifested by an alarm lamp on the front panel and an audio signal.

Detector Failure: Indicated by a rapid audible beep and meter reading of zero, instrument waits for 8 s after initial power-up sequence before giving indication to a detector failure (no count) condition

Front-Panel Potentiometers: Located under a removable front panel (not shown): alarm set, discriminator, HV adjustment, range calibration adjustments (x1000, x100, x10, x1)

High Voltage: Externally adjustable and variable from 200 to 1500 Vdc

Audio Output: Built-in unimorph speaker, audible click-per-deviation; beeps for every 1/8 second interval that is 2 sigma above background level, enabled or disabled by the audio ON/OFF switch, corresponds to the ALARM lamp initiation

Power: Two standard alkaline ˝D˝ cell batteries, secured in an isolated compartment

Battery Life: 600 hours

Construction: Cast and drawn aluminum with beige powder coat and silk-screened nomenclature

Size (H x W x L): 16.5 x 8.9 x 21.6 cm (6.5 x 3.5 x 8.5 in.) including instrument handle

Weight: 1.6 kg (3.5 lbs.), including batteries
