Temperature Measuring & Environmental Monitoring


The Oldham range guarantees uncomplicated peace of mind with undiluted focus on maximizing performance, quality and reliability, preserving human life and the environment.

The objective of gas detection is to measure the gas levels before a hazardous concentration is present.  Early warning provide outputs for emergency action plans.

Some of the risks presented by hazardous gas levels are explosion (EX), poisoning (TOX) and suffocation (O2).

Negative effects of toxic gases include irritation, chronic or irreversible tissue damage and narcosis of a sufficient degree to increase the likelihood of accidental injury, impaired self-rescue and/or reduced work efficiency.

Oldham's fixed and portable gas detectors are always application-driven and solution-oriented. Whether for a single application or multiple sites and areas, our durable gas monitoring solutions meet your unique industrial needs. Sperosens offers a broad range of gas detectors and controllers to satisfy most international certification standards such as ATEX, SIL (Safety Integrity Level), CSA, GOST and others.  Select the controllers, transmitters and accessories you need to effectively protect your people and your environment from hazardous gases.

Toxic gases and areas where one can encounter these gases can include:

Sperosens sell a wide range of fixed and portable gas detectors and monitors.  One of the most popular products is the BM25 wireless transportable Multi-gas detector. 

The BM25 packs the benefits of a fixed system area monitor into a rugged, user-friendly and transportable instrument. It was designed to detect one to five gases for mobile or temporary work applications, team protection, area surveillance or places where fixed detection systems are not suitable.

Powered by a NiMH battery pack, the BM 25 multi gas monitor offers up to 170 hours of continuous run time.  Other standard features include STEL and TWA values, as well as a data logging capacity of more than four months. Multiple units can be grouped using optional alarm transfer kits. This protects larger areas by transferring alarms from one BM 25 to the next.  An intrinsically safe trickle charger is available to maintain battery life for long-term area monitoring in classified zones.

The BM25 is durable and versatile. It is suitable for a wide range of industries including petro-chemical, refineries and pharmaceutical production.  Applications include plant maintenance shutdown sites, rig overhauls and perimeter-line surveillance.

The BM25 Wireless brings you freedom and flexibility while keeping the standard/fixed characteristics of the BM 25.

The MX32 controller monitors the information detected and reported by the BM25.  It was designed to centralize the information transmitted by the BM 25 over a wireless network and can display up to 32 measurements in real time. When a BM 25 signals an alarm, the MX 32 also goes into alarm mode and can, for example, control internal relays and order other monitors to transmit the alarm as well.

Any 5 of the following gasses can be detected simultaneously:  AsH3, CO, CO2, Flammable Gas (H2, CH4, Pentane etc.)  HCI, HCN, NH3, NO2, O2, PH3, SiH4, SO2

Because the new MX32 is both analogue and digital it can be used with either: 

·         Analogue transmitters

·         OLCT 10N, OLCT 80, OLCT 700/710 and iTrans2 digital transmitters

·         External digital modules (8-analog-input, 4- or 8-relay-output, 16-logic-input, 4-analog-output)

Up to 8 detectors and 10 modules can be used with the new MX 32

Oldham gas detection products meet all major international certification standardsand are used in numerous industries.  Applicationsinclude oil and gas, offshore exploration and production, petrochemical, food and beverage, water treatment, automotive, steel production, liquid natural gas, liquefied petroleum gas, pharmaceutical, power stations and many others.

Sperosens is the sole distributor of the Oldham range of Fixed and Wireless gas monitoring solutions for South Africa.
