The next delivery of phx42 chargers has been delayed until 5/1/23 (they were expected on 3/1).

Until the next delivery arrives, we can ONLY repair chargers received with the charging tip. We do not have any full assemblies to sell for repairs or RMAs.

We recommend reviewing the information shared in the September Tech Tip – phx42 Charger Care with your Technicians to avoid damaging your existing charger inventory.

If you have phx42 chargers currently in need of repair, please request an RMA. 

Please contact with any questions. 

Below are the two versions of the phx42 H2 Fill Port (LDAR# 42801). It is important to recognize the distinctions between each type and which one applies to your unit.

If your phx42 contains the v2 H2 Fill Port, but is missing the filter (as shown above in figure 3), please report an issue immediately.

The office will be closed on November 24th and 25th, 2022.

We will be back on Monday, November 28th, 2022.

Have a blessed and safe holiday.

LDARtools is excited to announce that we have signed a new Distributor Agreement with CleanAir Europe, the European subsidiary of Cleanair Engineering Inc. (USA), a world leader in the air quality industry since 1972. With 50 years of experience in the market, CleanAir Europe will now be offering LDARtools hardware products and services to customers based in Europe and Africa.

Here’s what CleanAir Europe has to say on the matter:

“We are very proud to enter into this partnership with LDARtools. CleanAir will not only supply LDARtools instruments, our team will be offering a global service with after-sales directly carried out in our workshops in France.”

Pump Clamp Tool
When installing pumps in the phx42, there is a chance of breaking barbs and the pump clip. To make this process easier, we have added a new pump clamp tool to the pump assembly.

This tool temporarily bends the tubing on the
pump assembly to assist with installation,
and is now shipping with the pump assembly.
If you already have pumps in your inventory
and would like to request the clamp tool,

The work instructions have been updated to
include this clamp, with YouTube videos
available for both types of pump


REMINDER: You must report an issue through the phxApp Self-check process and receive notification from LDARtools Tech Support before proceeding with any on-site repairs.

Please see this page from our friends over at Juniper Systems.

LDARtools is pleased to announce that we have completed the certification process for ISO 9001:2015 and ISO/IEC 27001:2013 Management Systems.

The Probe Testing Adapter was designed to help you identify the root cause of filter related errors such as:


How to use the Probe Testing Adapter

When a filter error is not resolved by following the on-screen prompts:

  1. Remove the probe, attach the Probe Testing Adapter with a clean probe tip filter, and run a self-check.
  2. If there are no errors, then the probe was the cause of the issue. Report the probe issue to LDARtools support.
  3. If there are errors, submit the issue to LDARtools and comment: “Self-check completed with Probe Testing Adapter”.

The Probe Testing Adapter (LDAR#4300) is now available on and will ship with phx42 tool kits (LDAR#4203) beginning April 1, 2021.

Enjoy your Easter Weekend folks. See you on Monday.

Many thanks to everyone who participated in our phx42 Probe Carrying Contest.
We had many entrants and have decided to name even more winners than we had originally

The Grand Prize of $250 goes to Bruce Phillips (with Lily/ERM). Bruce’s method features a
swivel carabiner (to allow the probe to lay flat in any position) and a d-clip to secure the probe
tip from swinging while climbing. (The attractive hoody was not part of the contest, but we
have had inquiries about where Bruce got it.)

Congratulations to Bruce!


We are also awarding $100 prizes to the folks who submitted these innovative ideas:

$100 Winners Company Cool Idea
John DeMaio and Brett Burt with Steve West Solvay Gear Keeper Lanyard allows the movement of the probe to full range but protects the probe from swinging while the tech is moving.
Denise Celestine HydroChem PSC Carabiner with ring hanging from backpack strap.
Shirley Barron HydroChem PSC Bringing probe hose through the opening in the top of the backpack- rather than leaving a gap in the zipper.
Wesley Nelson Team Chevron Great video showing the use of heat shrink, shock-absorbing lanyard and carabiner.


Note: the money will be donated to the Make a Wish Foundation on behalf of those individuals who could not accept it due to their employer’s policy prohibiting such foolishness!
