With increasing legislation and environmental demands pH is one of the most important online measurements that can automate processes, improve efficiency, minimise waste and save money.
Temperature Controls offers a variety of options, the BP9 Series of surface mounting controllers offer relay outputs for simple on/off control of dosing pumps or valves. The MPD53 or HPT63 series offer both relay and current outputs for proportional control in applications where accurate dosing is required.
The SP100 or SP200 pH electrodes are a standard 12 mm diameter pH electrode in the European PG13.5 format, with a double junction reference. They have detachable connection cables with a selection of mounting options available including a retractable system. For many applications the S400 Processprobe sensors are ideal and can be supplied with dip or inline mounting options. They can be used with virtually any pH meter and come in a choice of body styles with an option for a built in solution ground.
Dynaprobe pH electrodes are suitable for high temperature, high pressure industrial process applications. The patented solid state reference cell features the unique Ion trap design for extended service life in the most severe applications.
Self-cleaning and spray-wash adaptors can be fitted to all the styles of pH electrodes to reduce maintenance and improve electrode life, in applications where the pH electrode bulb is prone to coating. An isolating break tank with ball valve and suitable pump can be supplied to complete the cleaning system while the MPD53 and HPT63 instruments can be used to control the spray wash cleaning cycles.

Maintenance, Test & Measurement, Calibration
Cathodic protection keeps buried and submerged pipelines safe from corrosion, but verifying it traditionally means costly, hazardous manual site visits. Omniflex explains how a retrofit module brings remote monitoring to ageing transformer rectifiers without replacing functional infrastructure.

Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.

Maintenance, Test & Measurement, Calibration
WearCheck technical manager, Steven Lumley explains how static electricity accumulates in modern low-conductivity lubricants, why compact system designs and fine filtration make ESD more likely, and how to recognise the degradation it leaves behind.

Maintenance, Test & Measurement, Calibration
Using its clearance modification expertise, SKF helped a mining equipment OEM salvage spherical roller bearing inventory that would otherwise have been scrapped, confirming a new capability within its remanufacturing services and avoiding redundant procurement.

Maintenance, Test & Measurement, Calibration
WearCheck ARC division manager, Annemie Willer argues that the greatest threat to effective maintenance is no longer a lack of technology, but the gradual replacement of technical judgement by CMMS compliance, leaving no one owning the machine.
Read more...Nitration: the acid you didn’t see coming Wearcheck
Maintenance, Test & Measurement, Calibration
Nitration is as destructive as oxidation in many engines but far less understood. WearCheck technical manager, Steven Lumley explains how nitrogen oxide gases degrade lubricants, why the process is difficult to detect, and what oil analysis can reveal before damage occurs.
