MiniPID sensors

ION Science is available to support customers who have any questions about the transition away from Alphasense supply, and they can be assured there is no change in product quality, choice, or availability. The technology that sets the ION Science MiniPID sensors apart remains the same excellent product as always.

Since the purchase of Alphasense by AMETEK Inc late last year this long-term successful relationship has now sadly come to an end. Whilst we wish Alphasense well, we are keen that all customers know they can get a continued supply of ION’s unique patented MiniPID product directly from ION Science, global offices, and authorised distributors.

Customers who were purchasing MiniPID (PID-A1 or AH variants) through Alphasense or their distributors are now encouraged to source the world’s best PID sensor directly from our global ION Science offices. ION Science has worked hard with our committed suppliers to offer the best PID sensor lead times on the market. Coupled with our experienced and dedicated support teams ION will make sure your continued supply of MiniPID is seamless.

The types of instruments that ION Science sensors are used in should never be subject to compromise. Many can contribute to saving lives, preventing serious health effects, and protecting the environment. Equipping the right kind of sensor is essential to ensure your business remains compliant, safe, and certified.

MiniPID benefits include patented fence electrode technology, which provides market-leading humidity resistance and anti-contamination design for accurate detection in the harshest of conditions. Staying with MiniPID ensures you won’t compromise your instrument’s performance.

The MiniPID range of sensors goes beyond just one single base model. Our dedicated research and development team has engineered a suite of sensors based on market feedback to ensure that whatever a customer requires, there is a sensor fit for purpose. The product line includes:
