Holland Safety Equipment


Room Pressure Logger – OUT OF STOCK

SEPT. 15, 2022: This product is temporarily out of stock due to a shortage of pressure sensors. We anticipate being able to offer the RPL again by March 2023. Individual components may be available for a la carte orders.

Developed based on input from members of the Controlled Environment Testing Association, the RPL-10 from Associated Safety Products continuously monitors and logs the differential pressure between adjacent spaces in compounding pharmacy clean rooms, laboratories, isolation and operating rooms and other critical environments. Data is written to a USB memory stick that can be used to transfer to a spreadsheet application on a desktop or laptop computer. HSE recommends a weekly data transfer, but the file uses very little memory and the USB drive can hold months’ worth of information.

The RPL-10 also monitors door position and has an option for temperature and humidity monitoring. The unit helps comply with USP 797, OSHPD, CDC, CAG 003 and FDA 503b guidelines. For customers who want help with installation and on-site calibration (zeroing the on-board pressure sensor), HSE can recommend a CETA member cleanroom professional.
