I missed the Kenometers and realized very quickly that I needed an LPM to understand what I was seeing with my lasers. After reading the feedback from others who had purchased the LPM and researching who the buyers were, I decided to take a chance. Even though I am not very experienced, I thought that the situation warranted this post. This unit has been recently discussed in this forum and I just tested all of my lasers on a Kenometer (Thank you Scopeguy20) just five days ago.
I purchased the LPM from Laserbee on eBay, on April 9th. The unit arrived today (April 29) from Canada. It was packaged well in anti-static bubble wrap, bags, and a combination of foam and "peanuts" in a "double wrapped" box. The thermopile was wrapped separately from the meter. I unpacked the unit, attached the thermopile to the meter, and attached the 9V battery to the meter. It powered up fine. Laserbee states that the LCD is LED back light capable, but I haven't figured that out yet. It would help with ease of visibility.
The unit is small. The meter board is about 5.5cm x 7.5cm. The LCD screen is 3cm x 1.5cm. The thermopile is only about 7mm x 10mm.
I set the unit up and allowed it to adjust to the ambient temperature. What follow is the comparative measurements of my lasers. O = the labeled Mw from the manufacturer or dealer. K = What the Kenometer measured. L = what the Laserbee meter measured. The unit is advertised to be able to measure from 7mW-1000mW.
660nm
DX Dilda: O=200mW K=150mW L=152mW
532nm (DX style)
O=5mW K=19mW L= 15mW
O=30mW K=30mW L=30mW
O=50mW K=33mW L=30mW
O=200mW K=103mW L=100mW
593.5nm (XereX)
O=2mW K=2mW L=unable to measure
405nm
Lasershopuk O=<5mW K=11mW L=10mW
Milos O=14mW K=26mW L=24mW The Milos measurement was taken before he got his Kenometer
DrLava O=85mW K=95mW L=92mW
The Laserbee LPM measure fairly comparable powers to the Kenometer. They appear to maybe measure just a bit under, but I have been playing with these, with the same batteries for a week since the measurements were taken with the Kenometer.
The unit is small, The numbers on the small screen are difficult to see. Back lighting would probably help this. The small thermopile is a difficult target to hold steady on for my hand. Some sort of "holder" would solve this. The measurements, however, appear to be good. It will not measure below 7mW and I have nothing more powerful than 150mW to test it with, but it will do until Kenom finds another source for thermopiles
If Kenom or another of the more experienced members of the forum would like to play with this, I would be happy to send it off for your perusal. If not, I guess I need to figure out how to back light it and get to building a box for it.
Peace,
dave
