About Accumax Instruments
Accumax Instruments Private Limited is a process control instrument manufacturer based in Gandhinagar, Gujarat, India. The company was incorporated in August 1992 and has built instrumentation for Indian industry ever since.
What we do
We design and manufacture flow meters, flow controllers, piezometers and digital water level recorders, pH analysers and industrial IoT devices. Instruments are wet-calibrated in-house in an IEC/ISO/EN 17025 accredited laboratory before they ship.
How we got here
The company began in telecommunications, manufacturing under the OPTIMA brand as Quest Telecom Pvt Ltd. The electronics discipline that came from that work — precision, repeatability, instruments that keep working unattended — is what carried across when the business moved into process control instrumentation.
What we believe about specifications
Every datasheet on this site is downloadable without a form. An engineer should be able to decide whether an instrument fits before speaking to a salesperson. If a value is not published, it is because we have not confirmed it — not because we are holding it back.
Values
Quality, performance, delivery and economy — with maximum accuracy. That last phrase has been the company slogan for three decades and it is meant literally: the product is a number, and the number has to be right.
