What Process Instruments does
Process Instruments (UK) Ltd. (Pi), founded in 1998 and headquartered in Burnley, Lancashire, designs, manufactures, and sells water quality analyzers, meters, monitors, and controllers for municipal water utilities, wastewater plants, and industrial process customers. The portfolio spans residual chlorine, chlorine dioxide, ozone, pH, ORP, turbidity, dissolved oxygen, conductivity, fluoride, suspended solids, UV254, streaming current, peracetic acid, hydrogen peroxide, fluoride, and coagulation control parameters. Technical architecture centres on proprietary electrochemistry (amperometric membraned sensors in HaloSense, DioSense, PeraSense, PeroxiSense), photometric measurement (DioSense HR via Beer-Lambert), patented optical backscatter (SoliSense), and a conductivity-based alkalinity measurement method (AlkaSense) that requires no calibration. The CRIUS4.0 multi-parameter controller accepts up to 16 sensors with two-way remote internet communication and four PID control loops, while the smaller CRONOS controller handles up to two sensors; AutoFlush provides automated sensor cleaning to extend maintenance intervals.

Process Instruments product offering
Product offeringCore offering
Process Instruments designs, manufactures and supplies online water quality analysis instrumentation — analyzers, sensors, monitors and multi-parameter controllers — that continuously measure parameters such as residual chlorine, chlorine dioxide, ozone, pH, turbidity, dissolved oxygen, conductivity, fluoride, suspended solids, UV254, alkalinity and streaming current for water treatment, wastewater, industrial process and pool/leisure operators. The company sells directly from the UK, through European subsidiaries and a global distributor network in 50+ countries, and via private-label/OEM agreements under which other companies resell Pi products under their own branding.
Product overview
Process Instruments (Pi) is a global supplier of water quality analysis instrumentation providing a comprehensive portfolio of analyzers, meters, monitors, and controllers. The product lineup includes chlorine analyzers (HaloSense, DPDSense, Chloribrid®, DioSense, DioSense HR, HypoSense), pH/ORP/conductivity meters (pHSense, ORPSense, ConductiSense), turbidity and solids monitors (TurbSense®, SoliSense®), dissolved oxygen monitors (OxySense), ozone analyzers (OzoSense), coagulation controllers (CoagSense, DAFSense, StreamerSense), specialized analyzers for fluoride, peracetic acid, hydrogen peroxide, UV254, alkalinity, and particle counters. The core instrument controllers are CRONOS® (2-sensor capacity) and CRIUS®4.0 (up to 16 sensors with remote access), which serve as the platform for connecting and controlling all sensors. Add-on accessories include AutoFlush automatic sensor cleaning system and remote access via Control InSite. The company operates on a private-label model, meaning many products are sold under other brands through OEM agreements.
