TOTAL CONTROL

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.
