Water Quality Monitoring Systems

Continuous and automated water quality monitoring systems for process water, cleaning water, rinse water and drinking water in food production facilities. Water is a direct food ingredient and a critical process input — its microbiological and chemical quality must be monitored and documented under HACCP. These systems measure key water quality parameters in real time, logging data continuously and triggering alerts when values fall outside defined limits. Suitable for incoming mains water, borehole water, recycled process water and final rinse water verification.

Key Features

Inline Chlorine Monitoring

Inline chlorine monitoring systems for the continuous measurement of free chlorine concentration in process water, cooling water, CIP rinse water and sanitation solutions. Maintaining correct chlorine levels is a critical control point in many food production HACCP plans — too little chlorine means inadequate disinfection, too much risks chemical contamination of product or equipment damage. Inline monitors measure chlorine continuously and log every reading, providing real-time control feedback and a complete compliance record without the need for manual testing.

Key Features
ParametersFree chlorine, total chlorine, combined chlorine
Range0.01 to 20 mg/L depending on model
Response TimeContinuous real-time measurement
Output4-20mA, Modbus, digital relay
CalibrationAutomatic with calibration logging

Chemical Monitoring

pH & ORP Monitoring Systems

Continuous pH and ORP (oxidation-reduction potential) monitoring systems for process water, cleaning solutions, CIP circuits and sanitation applications in food production. pH is a critical parameter in acid and alkali cleaning cycles — correct pH confirms the cleaning solution is at the required concentration for effective sanitation. ORP measurement confirms the oxidising power of sanitizing agents, providing a reliable indicator of disinfection efficacy independent of chlorine concentration alone. Both parameters are logged continuously for HACCP documentation.

Key Features

pH Range0 to 14 pH units
ORP Range-1000 to +1000 mV
Accuracy±0.01 pH, ±1 mV

Air Quality

Compressed Air Testing Systems

Testing systems for the quality of compressed air used in food production — covering particulate contamination, oil content, moisture level and microbiological quality. Compressed air that contacts food, food-contact surfaces or food packaging is a direct food safety input and must meet food-grade air purity standards. ISO 8573 defines the cleanliness classes for compressed air quality; food production typically requires Class 1 or Class 2 for particulates and oil. Our testing systems cover all parameters required for compressed air validation, routine monitoring and supplier qualification.

Key Features
ParametersParticles, oil vapour, moisture, microbiological count
StandardISO 8573 compressed air quality classes
MethodsParticle counters, oil detectors, dew point sensors, impingers
TestingValidation sampling and routine monitoring

Pressure Control

Differential Pressure Monitoring

Continuous differential pressure monitoring systems for clean rooms, high-care zones, high-risk areas and controlled production environments in food facilities. Maintaining positive pressure differentials between clean and less-clean zones prevents airborne contamination from migrating into sensitive production areas — a fundamental principle of high-care facility design required under IFS, BRCGS and FSSC 22000. Differential pressure monitors measure the pressure difference across zone boundaries continuously, logging data and alerting maintenance teams when pressure drops below the required differential.

Key Features

Range0 to 100 Pa typical for food facilities
Accuracy±0.5 Pa

Particle Monitoring

Airborne Particle Monitoring

Continuous and portable airborne particle counting systems for food production environments — monitoring particulate levels in packaging areas, clean rooms, high-care zones and controlled production spaces. Airborne particles are carriers of microbiological contamination and chemical residues; elevated particle counts in sensitive production areas indicate a breakdown in air handling, filtration or personnel hygiene controls. Particle monitors provide real-time data on air quality trends, supporting HACCP environmental monitoring programmes and IFS high-care zone compliance.

Key Features

HVAC Hygiene

HVAC Hygiene Monitoring

Monitoring and inspection systems for HVAC (heating, ventilation and air conditioning) hygiene in food production facilities. HVAC systems that are not regularly inspected and maintained become sources of airborne contamination — biofilm in ductwork, mould on filters, and condensate in air handling units all represent microbial contamination risks. Our monitoring systems include differential pressure monitoring across filters to detect blockage, temperature and humidity sensors in supply air streams, and inspection equipment for ductwork hygiene assessment. Supported by documentation protocols for HACCP and IFS audit requirements.

Water Treatment

Water Filtration Monitoring Systems

Monitoring systems for water filtration performance in food production facilities — tracking filter condition, flow rates, differential pressure across filter beds and downstream water quality to confirm filtration is operating effectively. Water filtration is a prerequisite programme in most food facility HACCP plans for facilities using borehole, surface or recycled water as process inputs. Filtration monitoring systems detect filter breakthrough, channelling and exhaustion before they affect process water quality, with automated alerts and logging for maintenance scheduling and compliance documentation.
