Like Jon, I'm curious how he can claim better accuracy than the sensors themselves provide... but I'll just accept that as hype.
How long is the cable between the meter and sensor? Is it acceptable to legthen the cable, and what is the max length Klaus would recommend (taking into account I^2 R losses of the cable?
What is the power draw of the meter/sensor?
I agree the display could use some growth hormone therapy... I like the display on my Lambdaboy.
As I recall, the orignial Lambdaboy display consisted of about a dozen LED lights arranged in a row on top of the meter's metal case. You must have a newer version.
My previous posts completely neglected the sensors' accuracy limits. Thanks for mentioning this. The LM-1 ships with a Bosch LSU4 sensor. Here's a spec sheet from Bosch describing their LSU4 wideband sensor:
The specs are a little old (1999), but you can see in section 4.2 that the sensor's accuracy after 500 hours is rated at ±0.02λ.
