Novalog MC

The PC logging software stands out with easy useability. Certain Novasina aw-meters (LabMaster-aw neo, LabMaster-aw standard und advanced as well as LabTouch-aw advanced) can be directly connected to a computer by USB and/or RS232 interface. Measurement values can be recorded or protocolled on a PC by means of NovalogMC.

Benefits:
  • Easy useability
  • Compatible with all Win versions from XP to Win 10
  • Digital, fraud resistant measurement protocols
  • Detailled analysis of measurement curve development possible

SAL-T Humidity Standards

Humidity standards are used for verification and calibration of water activity meters. Our SAL-T humidity standards are about over-saturated salt solution according (Greenspan report, 1977). Although a defined air humidity is created over the surface of those standards which can be used for verification or calibration of a water activity sensor. The unique design of the salt standard allows re-use over a period of 3-5years (field experience) or even longer, depending on handling. This fact brings maintenance costs of a Novasina water activity meter to low levels.

Benefits:
  • Re-usable for low cost of maintenance
  • Safe design, avoids contact with liquid or salt
  • Various humidity standards for specific measurement ranges
  • Easy, optical control by user to verify salt standard status

Chemical Protection Filters

Certain volatile compounds as glycerin, alcohol and others will temporarily or permanently harm the Novasina sensor and/or will adulterate the measurement result. As a consequence, it might happen that the user thinks, the product is safe as water activity is below the limit, but as value is spoiled by volatiles, the real water activity value is higher. To avoid such uncomfortable situations and to get the real water activity value on display, chemical protection filters have to be used. Those filters have to be exchanged on a six to twelve month base, depending on the amount of volatiles in the sample and the amount of measurement performed per day. An exchange of the filter is an easy task and just takes one minute.

The selection help below should guide the user and finally show him the correct filter to be used for measuring the samples. 

Benefits:
  • Installed in a minute
  • Perfect protection of the sensor against volatiles
  • Specific filter for different volatiles

Sorptions-Isotherm (SI) Set

Sorption isotherm curves are helpful and one of the most powerful tool to understand processes as change in texture, crystallization and re-crystallization, phase transition, optimization of packaging and storage conditions of a procduct. They support as well stability modelling and defining specific water activity limits for a product to ensure product stability and best shelf-life period. 

The Novasina sorption isotherm set can only be used with a LabMaster-aw and allows a record of a simple curve at 11 points max. in the range of 0.04-1.00aw.Those curves are suitable for a first glimpse on the relation of water activity to moisture.

Benefits:
  • No need of a new, expensive device, current LabMaster-aw and Novasina humidity standards can be used
  • Easy handling
  • Simple installation
