When combined with any 2 L/min sample pump, the SPLIT2 Real-time Dust Monitor offers high flexibility for all dust monitoring applications.

The flexible and easy-to-use SPLIT2 is designed for personal or area monitoring for respirable or inhalable dust. SPLIT2 is a passive dust monitor that can become an active monitor/sampler by combining it with a 2 L/min sample pump, sampling head (GS-3 Cyclone or IOM Sampler), and preweighed filter for direct read-out and real-time profile of dust concentration and concurrent gravimetric dust sampling. The easy-to-read LCD continuously displays concentration in mg/m3, TWA, Max, Min, and STEL. Operate the SPLIT2 for over eight hours with NiMH batteries or use the AC adapter accessory for longer run times.

Used for real-time monitoring or concurrent gravimetric sampling, SPLIT2 is comfortable to wear and does not interfere with daily activity. When configured with a sample pump, the SPLIT2 with built-in belt clip can be placed on one side of a worker’s belt and the pump on the other side for maximum comfort. The sensor is mounted near the breathing zone for accurate breathing zone measurement. Handheld wand and tripod accessories are available for area monitoring.

SPLIT2 Calibration
SPLIT2 is calibrated using SAE fine test dust. The gravimetric filter sample collected can be used to correct real-time data, eliminating the problem of displayed results being accurate only if the dust monitored is similar to SAE fine test dust.
