The AquaTuff™ Model 35100 series with DuraNeedle, Bell Surface, or MicroNeedle Wrap&Stow™ probe is the right choice when accuracy is your top priority. Total System Accuracy™ ensures this instrument and probe combination will measure temperatures within a high accuracy. The probe is calibrated with the instrument to deliver a TRUE ±0.9F° accuracy for the 35132 and 35140 models and requires no additional calibration - ever! The heavy-duty patented probe cable is reinforced with Kevlar® and a metal braid that neatly wraps and stows around the instrument.

The 35132 with the DuraNeedle probes are best used for dense meats or soft frozen products. They also work well with soft foods and liquids.

Temperature Range: -100° to 500°F / -73° to 260°C
Temperature Accuracy: ±0.9F° / ±0.5C° total system at ambient temperatures between 68° to 86°F (20° to 30°C)

The 35135 with the Bell Surface probe is best used for taking measurements of any flat surface. Bell self-orients to a surface to give superior contact. Ideal for griddles and platens. With any surface measure, a small drop of oil or grease is recommended to aid in heat transfer to the bell sensor.

Temperature Range:  -100° to 500°F / -73° to 260°C
Temperature Accuracy:  +2.7°F & -6.3°F (+1.5°C & -3.5°C) on draft-free, flat, oiled surface in ambient temperatures between 68° to 86°F (20° to 30°C)

***
The 35140 with the MicroNeedle probe tip offers the quickest response with minimal impact on the product. Ideal for small products and semi-solid products.

Temperature Range: -100° to 500°F / -73° to 260°C
Temperature Accuracy: ±0.9F° / ±0.5C° total system at ambient temperatures between 68° to 86°F (20° to 30°C)
