RTM 1688-2 Portable Radon And Thoron Monitor Radiation Measuring Instrument

RTM 1688-2 Portable Radon And Thoron Monitor Radiation Measuring Instrument

The RTM 1688-2 portable HTHorium measuring instrument has high sensitivity and alpha spectrometry capability, allowing it to respond quickly even at low levels of hydrogen concentration and obtain thorium concentration in real time. The sniffing mode is used to search the radon source with built-in air pump, which can directly carry out the soil radon sampling and the measurement of water and hydrogen with one key operation. The direct printer provides on-site printing and can store 2047 sets of measurement data, and the panel button can switch different measurement schemes. In RTM1688-2, the data of each measurement cycle contains its own complete A-energy spectrum record

Technical parameters:

Approximately 250ml optimized high voltage chamber, using electric fields to collect ammonia daughters generated in the chamber to the semiconductor detector surface * short response time, using fast mode (95%, 12 minutes)

Increased sensitivity - double, using slow mode (Po-214)

Thorium (Rn-220) concentration can be measured

Long-lived radon daughters do not pollute the instrument

The energy spectrum of each measurement sequence a can be read separately to ensure 100% accuracy of the measurement

Measuring range: 0~10MBq/m3

Sensitivity: 3/7cpm/(Bq/m3)(fast/slow mode)

The radon concentration was measured at 200Bq/m3 with a statistical error of 10% (1Sigmal) and a 1-hour sampling interval

Radon concentration was measured at 10 bq /m3 with a statistical error of 25%(1Sigmal) at a 4-hour sampling interval

Temperature: -20℃~40 ℃

Built-in sampling pump: 0.30L/Min, continuous or intermittent sampling

Size Weight: 232×182×135mm, 3.5kg
