For 1000 Ω, Class A elements, change “100” to “1000” in model number, no additional price.
For lengths longer than 360 mm, change “0360” in model number to required length in mm and additional cost per 25 mm to price
(example: 500 mm = 0500, 425 mm = 0425).
For 3 mm probe diameters, change “M6” in model number to “M3” for 3 mm, no additional cost.
