  • The following models are particularly suitable for basic measurement where the result is required in Brix or refractive index. They are used to determine the sugar content in food or for monitoring processes in the industry (coolant monitoring, water-based mixtures). Alternatively the display can be switched to show Brix or the refractive index.

Main areas of application:
  • Industry: Process and quality control, lubricant control
  • Food processing industry: drinks, fruit, sweets
  • Agriculture: Determining the degree of ripeness of fruit for quality control during the harvest
  • Restaurants and industrial kitchens



Financing is available using KERN hire purchase - easy and convenient.

Hire Purchase gives you the option of purchasing any product from the range against a simple monthly installment. The product value is financed over the period of the agreement. On payment of the last installment, the ownership of the contract item automatically transfers from the contractor to the contractee.

The Hire Purchase Agreement can - if you so choose - be set for a period of between one and five years. All goods paid for in rates are covered by the warranty over the complete time period of the hire purchase

Compared with buying the product, KERN hire purchase offers the advantage that the initial financial investment is largely unnecessary. This is particularly relevant when purchasing a number of products, for example when refitting a laboratory, a company department or a hospital ward. In addition the monthly installments constitute a direct cost and the item does not have to be capitalised by the purchaser.


this is where you can search for spare parts for devices which you are already using. Ideally you will search using the serial number, which is given on the type plated under [SN].
Alternatively you can search by item number, which is also indicated on the type plate under [REF].
When doing this please make sure that the spare part is compatible with your device, by checking the specified scope of application.
