Review conclusionRecommendedWith reservations

Only in one review: Voltage 90 V (SIN90S).

Fnirsi FNB48: An accurate, feature-rich tester; the author especially liked its oscilloscope, offline logger, and PD emulation.

SIN90S: It meets its specifications, but accuracy is middling, the shunt drifts with temperature, and the buttons are very stiff.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
