FAQ
How does this compare to Erweka TBH / Sotax HT-1?
Erweka + Sotax are automated bench-top hardness testers with digital readouts, tablet feeders, and data logging for GMP-regulated pharma. This Pfizer-type handheld is manual operator-actuated — same USP <1217> compliance but slower for high-volume batch testing. Price differential: $225 vs $1,500-$3,500. For small-batch pharma + nutraceutical + compounding + teaching, handheld is fully adequate. For large pharma production QC with LIMS integration, invest in automated.
Is this USP <1217> compliant?
Yes — Pfizer-type handheld hardness testers are recognized in USP <1217> as one of the approved measurement methods (alongside motorized testers). Test data is directly comparable to compendial acceptance criteria for tablet breaking force.
How often do I calibrate?
Recommended annual calibration against certified reference weights. Send-in calibration service available with traceability certificate.
