Pita, the nervous, bashful lamb that was Trixie’s(the horse) “herd mate” has taken the long walk across our pasture to a place where the rest of us cannot go. All of the sad indications are that a pack of coyotes accompanied her on your final journey. Needless to say, we were all saddened by the loss- none of us more so than Trixie- who is just now starting to rebound from the grief.

Pita came to live with us several years ago. The immediate plan was for her to be here for just a couple of weeks. That would have been the last two weeks of December- leading up to the Christmas Dinner at Rex and Valerie’s house. But when Valerie learned that the “lamb” she had requested from Martin was actually going to require killing an actual lamb, her appetite waned for mutton and Pita was given an indefinite reprieve.

She delighted us, for years, with her dogged devotion to being Trixie’s wing-lamb.
She brought countless smiles to our faces and absolutely no veterinary bills. She was the perfect companion for Trixie. And we miss her.

We can only hope that the coyotes appreciate that they were able to finish the job that Valerie had originally envisioned.
May she rest in tender grass…”

We recently delivered the 2000th phx to a lucky customer. Needless to say, we are pretty excited about that.

We would like to say thank you to all our suppliers, distributors, and most importantly, our customers.

The Warehouse will be Closed on Christmas Eve (Friday, 12/24), but will be open on New Year’s Eve (Friday, 12/31).


Price increases are not surprising. We have never had an across-the-board price increase. But that time has come.

In spite of rising prices for virtually everything we need, we have continued to invest in making our products the most innovative and valuable tools for the LDAR industry. The time to reckon with those costs has come.

Effective January 1, 2022, our prices will change as follows:

There will be a 10% Increase on:

  1. phx42
  2. SpanBox (all models)
  3. Fill adapter
  4. Minimum repair fee for phx21
  5. Repair fees on phx42 and phx21
  6. All training fees and other services
  7. Calx.x License fees.
  8. Price increases triggered by specific vendor costs will be passed on as we have in the past.

There will be no price increase for LTI Mobile products.

Pricing for Chateau will be handled on a quote-by-quote basis.

If you have any questions, please feel free to contact me directly.

Through it all, we appreciate your business.

Tomorrow (Tuesday, 9/14), the Warehouse will be closed.
We will make a decision about Wednesday (9/15) on Wednesday morning.

Wish us luck and stay dry yall!

On August 30 we had another Zero phx FID Day in our lab! (Actually, we had one phx42 but since it was going to be an extended repair, we had provided a free loaner to the customer – so we smile and consider that a victory.)

Normally, we would have a Brownie Celebration. This would be our 14th Brownie Celebration.

About 1200 phx21s and 787 phx42s are in service and NONE in our repair lab. THAT is success.

But since we just had a Celebration to celebrate our ISO 9001 and ISO 27001 certification success we have decided to do something different.

Rather than send brownies, we are going to send $42 gift cards to the Level One Certified techs at designated sites for our Domestic users. The Level One Techs can use that to buy cookies or pizza or whatever they want to for the other Techs at their sites. Or they can take their sweetheart out for dinner. That’s up to them.

Over the next couple of weeks, we will be reaching out to all the Level One Techs to arrange to send the e-cards to you. We realize that some of you may not be able to receive these gifts- due to your employer’s or client’s rules about gifts or such. If that is the case, we will make a contribution to a Hurricane Ida relief fund on your behalf.
Thanks to all our Level One Certified Techs for helping us achieve this great success.

You will be hearing from us. Soon.

On December 30, 2020, there were NO phx21 or phx42’s in our Repair lab.This is our fifth Brownie Celebration since introducing phx42.
We are so excited!

Thank you to all the phx21 & phx42 Level 1 Techs and users.
Continued teamwork and diligence, helped make this all possible.
We hope you’ll be a part of the celebration

We will be sending our famous “world’s greatest brownies” but the brownies will not be required to wear masks!
