We’re excited to unveil the latest evolution in our probe lineup — a next-generation design that’s built to outperform and outlast.
- Stronger Than Ever: Engineered with rugged materials, this probe is tougher and more durable than V2, making it ready for the harshest conditions.
- Simplified Maintenance: Say goodbye to downtime. Our new design is easier to repair than previous models, with streamlined access to the sample tubing.
- Field-tested and tech-approved, this model has already proven itself where it counts — in real-world use.
This is the probe you’ve been waiting for.
v3 Probes will begin shipping with new phx42s purchased after 7/15/25. If you currently have an older model and would like to upgrade, contact sales@ldartools.com.
The future of durability is here.

At a time when price increases are becoming more common, a price reduction on a quality product is always a welcoming breath of fresh air. As of February 7, 2025, we have reduced the price of the SpanBox Lite 530 from $4,198.69 to $3,653.50. This reduction is a result of the recent retirement of the SpanBox Lite 510; compensation for reducing the number of products available in our SpanBox5 series.
Paired with our Cal5.0 software, the SpanBox Lite 530’s support for five calibration gases and up to three phx42s ensures you receive the same experience as with the Lite 510, but with the added convenience of being able to calibrate multiple phx42s.
For more information on the SpanBox5 and Cal5.0, please visit our SpanBox5 page, or contact our Sales team at sales@ldartools.com.
We here at LDARtools are standing by to help create an LDAR system that works for you, and as always, we appreciate your business.
We are thrilled to announce there are more than 1,385 phx42 FID analyzers* worldwide.

*Also commonly known as Toxic Vapor Analyzer or TVA. This is a misnomer, but also a term the industry has accepted to describe portable FIDs.
