The Janetsons ThinProbe refractometer outperforms standard refractometers by delivering temperature measurements fast enough for industrial feedback control, providing perfect temperature compensation, and cutting installation costs in half.

Key Comparisons: ThinProbe vs. Standard Refractometers

JANETSONS THINPROBE REFRACTOMETER

Feedback control

Fast-response measurements enable real-time feedback control

STANDARD REFRACTOMETER

Feedback control

Too slow; cannot maintain stable control

JANETSONS THINPROBE REFRACTOMETER

Temperature compensation

Highly  Accurate; measures refractive index and temperature at the exact same point

STANDARD REFRACTOMETER

Temperature compensation

Lower accuracy; prone to lag

JANETSONS THINPROBE REFRACTOMETER

Weight

0.6 kg (1.3 lbs); lower mass enables faster temperature response

STANDARD REFRACTOMETER

Weight

At least 2.4 kg (5.2 lbs); slower temp. feedback

JANETSONS THINPROBE REFRACTOMETER

Probe Diameter

12 mm;  optimized for quicker response and strength

STANDARD REFRACTOMETER

Probe Diameter

Thicker; slower thermal response

JANETSONS THINPROBE REFRACTOMETER

Installation Cost

Lower, combines two measurements into one

STANDARD REFRACTOMETER

Installation Cost

High; requires two separate instruments

ThinProbe Core Advantages

High-Speed Temperature Tracking: Low mass (0.6 kg) and a thin Ø12 mm design eliminate thermal inertia. This allows the probe to react instantly to temperature shifts.
Industrial Durability: The Ø12 mm probe diameter balances thermal speed with structural strength to withstand heavy process flow forces.
Representative Concentration Flow: Total immersion in the main flow ensures the liquid wetting the prism 
surface accurately represents the entire batch
Dual-Function Savings: ThinProbe replaces the need for a separate temperature sensor and refractometer, 
cutting hardware and installation expenses by 50%.

Temperature measurement

Comparison between traditional refractometers and ThinProbe

A standard industrial temperature measurement is made by the temperature element protected by a thermowell with diameter of 1/2” (12 mm), the same diameter as ThinProbe.
