RDS-30 Rem/Sieverts Dose Rate Survey Meter

RDS-30 Dose Rate Survey Meter

The RDS-30 is a Digital Handheld Dose Rate Meter designed for a wide range of applications involving a possibility for abnormal radiation levels. Compact, lightweight, waterproof, its performance and its user friendly interface make the RDS-30 perfectly suited to radiation survey in field conditions, in nuclear industry and for protection against radiological hazards by personnel, who may be exposed to gamma and/or X-ray radiation in their work.

RDS-30 provides sequential alarms for fixed dose rate values (programmable by CSW configuration software via IrDA link) and the possibility to store dose rate events into the histogram memory of the meter. The use of a CSW software is required for downloading the data into a PC via IrDA port.

RDS-30 is microprocessor controlled. The user interface consists of one push button and an easy-to-use menu structure that displays information in the LCD of the meter. The six-digit display shows the dose rate and various messages. Different alarm situations are indicated by a combination of audio-visual effects in the LCD and a buzzer (dose rate 1, dose rate 2, low battery, defect, dose rate overflow).
