Features
It concerns an apparatus measuring the calcium carbon rate in the samples of sediments or drilling core by the measurement of the carbon dioxide pressure emitted after an hydrochloric acid injection (Method based on ASTM D4373-02). For each sample it gives the mass, the rise pressure curve on 100 points and the calculated rate. By eliminating tedious handling of the Chittick apparatus, it strongly reduces times of measurement. Moreover connected to a PC, it allows a data processing by computer.
ADVANTAGES
- Samples - 90 mg to 1,1 g in 3 ranges
- Removable carousel of 20 samples
- Automatic management of the system by a microcontroller
- Possibility of optimizing the parameters of measurement manuall
- Hydrochloric acid proof PVC case
- Delivery with an adapted scales
- Optional extra: PC software for data processing by computer.
- Automatic acquisition of the samples masses resulting from a scales with a RS232 connection or manual acquisition directly by the keyboard
- Output the data and results toward a PC using another connection RS232 with the possibility of direct reading of the masses and rates on the calcimeter screen
- Automatic adjustment of acid quantity and measure volume according to the sample mass
- Conversational programming by a 16 keys keyboard and a LCD screen of 2 lines
- Possibility of choosing the number of samples to be measured
- Choice of the measurement time according to the quality of the sediments
- Display of the pressure on LCD screen during the reaction
