Ordering Information
The CLP Calibrators can be ordered for a specified Helium Leak Rate within a wide range of values. When ordering or requesting a quotation, please provide the Part Number, confirm the Fitting needed, and state the specific Leak Rate requested including your preferred leak-rate units. Also, please specify the Manufacturing Variance ("Tolerance") that you can allow on that Leak Rate. The usual manufacturing variance is +/- 40% of the requested rate. An example specification is 2.0x10-8 atm-cc/sec +/- 40%. Alternatively, the allowable values as manufactured can be specified as 1 to 3x10-x, 4 to 6x10-x, or 7 to 9x10-x in a Leak Rate Range listed below.
Also, a "Special Range" manufacturing variance is available of +/- 15% of the requested rate. For this special variance, an "-SR" is added to the end of the Part Number and there is an additional cost. In all cases, the leak rate provided will be within the selected manufacturing variance and will be as close as we can make it to your specified rate. The actual rate, as calibrated, will be recorded on the Calibration Tag and the Certifications.

Part Number Build-Up
The CLP Series Part Numbers are constructed as follows:
CLP-X-HE-YYYY-ZZZ
where X = the code for the Leak Rate Range required,
where YYYY = the fitting required
and ZZZ = the code for the reservoir size.
The addition of a Fill Valve is required on all leaks in the mid 10-6 range and for all 10-11 and 10-12 leak rates. In these cases, -MFV is added to the part number for the premium all metal valve. For the large 10-6 leaks a Teflon-packed metal fill valve can be used for some non-UHV applications, and -WFV is added to the part number.
