The OdaLog® is a portable gas detector specifically designed for the wastewater industry, manufactured by App-Tek International – the industry-proven gas detection specialist for harsh environments.
Due to the nature of the environment in which the instrument has to operate, the OdaLog® is designed to be intrinsically safe, corrosion-resistant, robust and able to log data for extended periods of time. The OdaLog® is primarily used at a location close to the source of Hydrogen Sulphide (H2S) emissions such as those found within sewerage pumping stations, receiving manholes and inside sewer collection lines. Also, it can be used as personal safety device for confined spaces (OdaLog® 7000 MkII).
The OdaLog® interfaces with App-Tek’s own proprietary easy to use OdaStat-G software and allows users to set up the OdaLog® and download logged data in a user friendly format. All data is presented in tabular or graphical form to highlight significant variations in H2S levels over time. The OdaLog® uses IrDA (Infrared Data Association) technology to communicate between the logger and its proprietary OdaStat-G software.
App-Tek International is pleased to announce the release of the OdaLog® Type RTX:
The OdaLog® has been specifically designed to withstand harsh environments typically found in the Wastewater Industry. The OdaLog® is primarily used by locating it at or close to the source of Hydrogen Sulphide emissions such as within sewerage pumping stations and receiving manholes. Its purpose is to log gas levels to help control levels of H2S gas in sewerage systems and treatment plants for later reviewing using OdaStat-E software application.
Applications:
The OdaLog® RTx is the next generation of OdaLog® gas logger that utilises an in-built GSM modem to transmit real time gas concentration data to a dedicated Internet server that is remotely accessible using the latest OdaStat-G software application.
Applications:
Hydrogen Sulphide can be smelled at very low ppb levels of H2S and has a strong, offensive and nuisance odour. This odour can be the source of numerous complaints from residential and business communities and in many areas, H2S levels are regulated to ensure emissions are within acceptable levels. For this reason, the OdaLog® Low Range H2S Logger was developed. With a measurement range of 0.01-2.00ppm and long term logging capability, it is one of the most accurate and effective H2S odour management tools available.
The Low Range H2S Logger is designed for indoor and outdoor use and will record levels of H2S at a sampling interval between 10 minutes and 1 hour for at least one week on a single C-size alkaline cell. This allows operators to deploy the Low Range Logger ahead of time at the site of a problem or facility perimeter so that odour problems can be measured and recorded as they occur. The Low Range H2S Logger has an in-built sample pump and can log up to 30,000 data points.
Typical Applications:
The OdaLog® 7000 MkII multi-gas unit is based on the proven OdaLog® Logger design and had been designed to be a single gas monitor, or to monitor up to 6 gases depending on the combinations required.
The instrument has very distinct audible and visual alarms with huge data logging capacity as well as the capability to be used as an area monitor further sets this unit apart from competitive products as it is Zone 0 certified.
Typical Applications:
The OdaTrak™ 4 to 20mA adapter was primarily designed as an interface between the OdaLog® gas Logger and industrial control systems for the purpose of continuous, real-time optimisation of chemical dosing odour control systems and connection to telemetry and other systems.
The OdaTrak™ 4 to 20mA adapter reads gas concentration data sent from an OdaLog® gas Logger over a fibre optic cable, deciphers the data, and then outputs the corresponding 4-20mA loop analogue signal. This allows the OdaLog® unit to be interfaced to control and telemetry systems providing real-time gas data. This signal could be used to optimise chemical dosing, trigger alarms, control ventilation fans, or interface to telemetry systems etc. The OdaLog® Logger can still be used as a standalone data-logging instrument if required.
Fault detection - The OdaTrak™ has the ability to detect for a loss of OdaLog® data over a predetermined period of time and will output a fault state on the 4 to 20mA line when that time limit has expired. The fault current is 3.5mA.
Suitable for harsh environments - The fibre optic cable connector features an O-ring seal to prevent the ingress of dust and liquid, and the OdaTrak unit is fully sealed.
Quick and easy installation - The OdaTrak has an M20 thread machined as part of the housing. Simply mount through a 20mm hole or threaded junction box entry.
Data logging - All of the usual OdaLog® functions, including data logging, are available while the 4 to 20mA link is active.

The App-Tek Gas Dilution System (GDS) is an easy to use electronic device designed to take a known calibration gas or gas sample and dilute it to lower concentrations.
The diluted gas output can be used for calibrating gas detection instruments or can be presented to gas measuring equipment in an appropriate range to enable the sample to be analysed.
The GDS also equilibrates the relative humidity level of the diluted gas to close to ambient with its inbuilt Nafion® tubing for both the SOURCE GAS and the DILUTION GAS inputs.
Gas output flow rates of 250 ml/minute in 10% dilution steps or 500 ml/minute in 1% dilution steps can be selected as required and the dilution rate can be varied up or down by using the two push buttons on the front while the GDS is running.
The GDS has an inbuilt rechargeable battery pack and can be run from the charger even when charging.
The App-Tek Gas Dilution System offers scientists and technicians the ability to perform “on-site” gas dilution in a small, inexpensive and easy to transport package.
