LDARtools has delivered 50 phx42s


We are excited to announce that the 50th phx42 was shipped May 24th. This is only the beginning.  

50 units sold

We will be the first to admit that manufacturing is hard. We have had learning opportunities (mistakes) on early units that made it to customers. We have worked hard to determine the cause of these issue


s and have successfully identified and addressed the cause of each one. There will be more to learn and we are ready.

There have also been many versions of our software and 3rd party handheld software that needed testing and revisions. The Inspection Logic, Guidewire, and CNTRAL Platform development teams have been great to work with and are committed to building the best customer experience for our mutual customers.

Being an early adopter can be a difficult thing and we thank every one of our phx42 customers for their willingness to help us improve the product, our software and the 3rd party software compatible with phx42.

LDARtools Q1 Corrective Action Report

How a 5-Minute Quick Solution will keep your phx21™ in the field longer

LDARtools’ highly trained technicians work on hundreds of phx21 analyzers in the course of a year. This is what the professionals had to say about maintaining your ph21.

So, while there are no perfect scenarios, we believe we can help you improve your LDAR program with some quick simple tips.

Let’s start with the good news; over one third, thirty-eight percent (38%), of all phx21s sent in for repairs were due to normal wear and tear. In other words, the Technicians in the field are doing everything correctly, however, in these cases, the repairs were above Level 1 Training. The pie chart below illustrates the data collected from our quarterly report.

Q1 Corrective Action Report

The #1 most important thing you can do to prolong the use of your phx21

A third of the phx21s that visited our shop this quarter were due to filter and O-ring abuse. Performing a quick visual inspection of probe O-rings and inlet filters before going in the field will keep your phx21s in the field longer!

Tech Tip: O-rings (LDAR #918) and Inlet Filter (LDAR #825) can be easily misplaced or damaged. Keep plenty around. The phx21™ User Manual (Version 12.3, pg. 11)

Perform visual inspections of probe O-rings and inlet filters before going in the field.

Secondly, properly applying silicone grease (LDAR #881) to probe O-rings on a weekly basis will prevent cracking.

Trust your handheld when it tells you to replace probe filter, the phx21 PDA app will automatically display warning signs if the filter needs attention.


Don’t forget to perform these quick 5-minute inspections of your filters and O-rings and keep your phx21 in the field longer!

Congratulations to everyone that maintains their phx21 in tip-top shape!

Thank you Wayland and company at Arkema Clear Lake

Thank you all for being the best part of our Brownie Celebration. As you know, we started this tradition back in May 2015 when Rex had the idea of rewarding technicians for helping us clear our phx21 Maintenance Board. We have celebrated many Brownie Celebrations due to our experienced Level 1 Certified Repair Techs, enhanced automated support system, and improved technician training methods. When a Brownie Celebration is announced we take a head count of technicians at phx21 sites and celebrate with you by mailing out brownies!

6th BC final numbers v2


Over the years we have shipped out over 10,000 brownies to hundreds of customers and had lots of fun doing it! Nothing makes us happier than to see our customers enjoying the brownies! So a special thank you to Wayland and his team at Arkema-Clear Lake for sharing their picture with us!

Keep a lookout for the next Brownie Celebration and don’t forget to share, your picture with us!

phx42 Status Update

Our first run of boards at the mainboard production facility uncovered a minor problem with the Analog-To-Digital converter (which allows us to measure FID readings). This sensor is so sensitive (to read low concentrations) that the standard production and subsequent cleaning process is not sufficient. The sensor was measuring microscopic flux residue from the board’s production. This was not initially detected on the first batch of 20 final production boards that had been assembled.

Our working assumption is that the first batches were cleaned by the engineers who designed the boards, while the latter batch was cleaned as a part of the production process. The difference in result, when reflected in electrical currents measured in pico amps, proved troublesome.

The problem manifested on approximately 50% of the units. Unfortunately, the boards must go through a time-consuming assembly, testing, and potting process, then installed in an actual phx42 before the issue can be discovered.

We have modified this part of the process to address the issue and expect the second batch of updated boards to go into phx42s on 4/12.


Assuming that we have effectively resolved this issue and we achieve a 100% success rate on that batch, we will return to our accelerated production schedule of 20 – 25 phx42s every two weeks.

We have currently delivered and placed into service 4 units in the US and a unit in Taiwan. All deployed units are performing according to expectations.


Please note: your site delivery schedule is dependent on the completion of the Pre-Delivery Checklist, software availability, and installation schedule. Please contact sales@ldartools.com with any questions.
