Handheld Particle Counter
Model 3888 & 3889
The Model 3888 (3-channel) and 3889 (6-channel) Handheld Particle Counters utilize the same, proven parts
that made the original Handheld Particle Counters so reliable. The instruments meet/exceed new ISO 21501-4
Standards and are fully RoHS compliant. The instruments now have a base/stand for advanced communication
capabilities (Wi-Fi, Ethernet, RS485), a larger, full color touchscreen display, and enables real time monitoring
while connected to a PC.
Applications:
- Monitor and Verify Cleanrooms (Pharmaceutical, Semi Conductor, Food Industry)
- Monitor Surgical Rooms
-Filter Testing
-IAQ Investigation
-Data Center Cleaning
