The 5609 comes with a one-quarter inch (6.35 mm) diameter sheath in lengths of 12 inches, 15 inches, and 20 inches; or with a 6 mm diameter in lengths of 300 mm, 400 mm, or 500 mm.\u003c\/p\u003e\u003cp\u003eWhen looking for improved response time and reduced stem effect in shallow immersion, look for small diameter probes, because the measurement error called stem effect is caused by the diameter of the stem rather than the length of the stem.\u003c\/p\u003e\u003cp\u003eBoth of these probes have Inconel™ sheaths and are made using a special manufacturing process, giving them great precision over a wide temperature range. The sensors for these probes are reference-grade platinum and feature four-wire connections with less noisy measurements than two-wire counterparts.\u003c\/p\u003e\u003cp\u003eAs standard, each probe includes its resistance value at the triple point of water. If calibration is desired, you can order an accredited calibration from our laboratory; lab code 200348-0. On the report of calibration, you’ll get the test data and the ITS90 calibration coefficients that you can easily input into any Fluke Calibration thermometer. If you order your probe with an smart connector, we’ll program the coefficients directly into your connector, which loads the coefficients for you when you plug it into our 1524 Handheld Thermometer.\u003c\/p\u003e\u003cdiv\u003eModels\u003cul\u003e\n\u003cli\u003e5608-9-X\u003c\/li\u003e\n\u003cli\u003e5608-12-X\u003c\/li\u003e\n\u003cli\u003e5609-12-X\u003c\/li\u003e\n\u003cli\u003e5609-20-X\u003c\/li\u003e\n\u003cli\u003e5609-300-X\u003c\/li\u003e\n\u003cli\u003e5609-400-X\u003c\/li\u003e\n\u003cli\u003e5609-500-X\u003c\/li\u003e\n\u003cli\u003e5609-9BND-X\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e“X” in a model number denotes the probe termination (e.g. A = INFO-CON for 914X, B = bare wire, D = 5-pin DIN, G = gold pins, J = banana plugs, L = mini spade lugs, M = mini banana plugs, P = INFO-CON for 1523\/1524, S = spade lugs).
