This is for users with high throughput (production) laboratories who like to see the statistics (STATS) for the operation. Printing means a serial output on Port D1 in a printable form and STATS means statistic information. The statistic info comes from the Event Log. STATS are available for : Start …
The CAL3K was designed to work as a standalone system. That means it does not need a computer to operate. This is achieved by loading the “DEFAULT” settings (which we do before shipping). The default settings are what we think average settings, and are good for all kinds of determinations. …
All CAL3K units have the same connectivity as the other family members. The family members are : CAL3K-AP CAL3K-A CAL3K-U CAL3K-F A view of the rear panel confirms : A balance input port, settable baud rate from 1200 to 38400 baud A USB 2.0 port for short distance (laptop) connection …
The CAL3K box (the calorimeter) is always required as a minimum system. The following system options depend very much on your workload and the way samples are performed. Items like constant or burst workload influence the system options (and cost) largely. All system components can be purchased upfront or later …
Calorimeters require a high temperature resolution because the result has a high resolution. Despite the inaccuracies in the sample preparation a calorific value (CV) is expressed with 3 or 4 decimal digits. The following components affect a CV of, let’s say, 26KJ/g as follows : Deviation From Mass 0.0001g 0.5g …
The cooler is the slowest system component. We have optimised it as best we can; but it is slow! It cools a vessel down by blowing air at it. Not a very efficient way, BUT very resource friendly and economical. Cooling the vessel with air is possible because the temperature …
The CAL3K system uses the SMART CAL3K bomb vessel. The bomb vessel is the first of its kind, and is the heart of the CAL3K system. Its sophisticated design allows the temperature to be measured to six decimal places in degrees Celsius. The vessel is an intelligent (SMART) vessel with …
The CAL3K systems can operate with a RSD less than 0.1. The operating speed and RSD are somewhat related to each other. The best RSD is available in the 2.6 to 3.5 minutes. More accurate (%RSD) determination eliminates multiple sample repeats. This feature applies to the following CAL3K Systems : …
The determination speed was improved due to better initial firing conditions and vessel material technology. A determination speed of 5 minutes from bomb insertion to bomb removal are standard cycle times. Four minute cycle times are achievable, with a little external help. This feature applies to the following CAL3K Systems …
This is a conventional term, but related to the heat capacity. The Bomb factor is approx. 1 KJ/C. In practice this means that 0.5g Benzoic Acid results in ~13.2°C rise. Then the calorific value CV=13.2C / 0.5g x 1KJ/C = 25.4KJ/g This feature applies to the following CAL3K Systems : …
